Exact plane symmetric black bounce with a perfect-fluid exterior obeying a linear equation of state
We investigate an exact two-parameter family of plane symmetric solutions admitting a hypersurface-orthogonal Killing vector in general relativity with a perfect fluid obeying a linear equation of state $p=χρ$ in $n(\ge 4)$ dimensions, obtained by Gamboa in 2012. The Gamboa solution is identical to the topological Schwarzschild-Tangherlini-(anti-)de~Sitter $Λ$-vacuum solution for $χ=-1$ and admits a non-degenerate Killing horizon only for $χ=-1$ and $χ\in[-1/3,0)$. We identify all possibl…

Virtual invariants of Quot schemes of points on threefolds

Virtual invariants of Quot schemes of points on threefolds
We construct an almost perfect obstruction theory of virtual dimension zero on the Quot scheme parametrizing zero-dimensional quotients of a locally free sheaf on a smooth projective $3$-fold. This gives a virtual class in degree zero and therefore allows one to define virtual invariants of the Quot scheme. We compute these invariants proving a conjecture by Ricolfi. The computation is done by reducing to the toric case via cobordism theory and a degeneration argument. The toric case is solved …

Perfect Secrecy in the Wild: A Characterization
Alice wishes to reveal the state $X$ to Bob, if he knows some other information $Y$ also known to her. If Bob does not, she wishes to reveal nothing about $X$ at all. When can Alice accomplish this? We provide a simple necessary and sufficient condition on the joint distribution of $X$ and $Y$. Shannon's result on the perfect secrecy of the one-time pad follows as a special case.

To dig slightly deeper here, I think that there's a feedback loop between "fall in love/wait for your perfect match (and by the way girls the only career you should aspire to is the literally unattainable 'princess'" Disney stuff and this "my characters are complex I'm so sophisticated; they suffer but it's not intolerable and their lives are good enough despite the imperfections" crap that gets praised as so evocative of the human condition. In fact, I think it merely evokes the condition of its authors & fans who were poisoned by the Disney in their youth and who have remained bad as relationships ever since, though this is not exactly their fault. In any case, their white middle-aged wisdom-shaped-but-quite bitter and intricately-constructed-so-it's-hard-to-see-the-really-untrue-character-facets work ends up keeping their audience within the "romance is luck" cult by way of reassuring them that a middling romance with lots of doubt and complications is "just life" even though the author doesn't actually have any broader perspective on what life is than anyone else.
This has turned into a bit of a rant, but I think I'll just add that reading Mama by Nikkya Hargrove just before Dream State helped immensely to see how the distant & awkward parent-child relationships of the latter are not a product of human nature but instead of white western culture & capitalism.
(The defeatism about climate change is a whole nother dimension of wrong about Dream State, by that's a separate rant.)

A "trembling hand perfect" equilibrium for a certain class of mean field games
We study a particular class of mean field games whose solutions can be formally connected to a scalar transport equation on the Wasserstein space of measures. For this class, we construct some interesting explicit examples of non-uniqueness of Nash equilibria. We then address the selection problem of finding rational criteria by which to choose one equilibrium over others. We show that when the theory of entropy solutions is used, we can obtain explicit error estimates for the ``vanishing noise…

Calamus 31 What ship, puzzled at sea
Just when I'm beginning to think I have some facility reading Whitman I meet a head-scratcher like this. Taken literally this is a poem about Whitman offering to guide a boat at sea, or to offer military troops to a besieged city.
But presumably it's a metaphor. Whitman offering to guide and help those in need. It's a little strange?
Hard-pressed for a gay reading here but I'll focus on this:
Here, sailor! Here, ship! take aboard the most perfect pilot.
Here Whitman is offering himself to a sailor, naming himself the most perfect pilot. I could imagine that being a metaphor of sexual mentorship. But honestly that's a stretch.

Fun fact from Japan! We have a saying "郷に入っては郷に従え" (gō ni itte wa gō ni shitagae) which is our version of "when in Rome, do as the Romans do." Here "郷" (gō) means "village" or "hometown" - equivalent to "Rome" in the English proverb.
The funny part - in Japanese, "郷" (gō) sounds exactly like "Go"! So Go programmers here often joke: "Goに入ってはGoに従え" (Go ni itte wa Go ni shitagae) or "When in Go-land, follow Go's ways." A perfect bilingual pun that just works!

Ising versus infinite randomness criticality in arrays of Rydberg atoms trapped with non-perfect tweezers
Chains of Rydberg atoms have emerged as an amazing platform for simulating quantum physics in low dimensions. This remarkable success is due to the versatility of lattice geometries achieved by trapping neutral atoms with optical tweezers. On a given lattice, the competition between the repulsive van der Waals potential and the detuning of the laser frequency brings the atoms to highly excited Rydberg states, leading to a variety of exotic phases and quantum phase transitions.

Modern Minimal Perfect Hashing: A Survey

It may return an arbitrary result for any key not in $S$ and is called minimal if $m = n$. The most important parameters are its space consumption, construction time, and query time. Years of research now enable modern perfect hash functions to be extremely fast to query, very space-efficient, and scale to billions of keys. Different approaches give different tr…

Within this model we prove two theorems. (1) Indetectability Theorem. If such a hypervisor existed, no guest-level program, measurement, or timing test could distinguish it from native execution; all traces, outputs, and timings would be identical.

In this model, it is known that: (i) proportional allocations can be computed using $O(n \log n)$ queries, and this is optimal for deterministic protocols; (ii) envy-free allocations (a subset of proportional allocations) can be computed using $O\left( n^{n^{n^{n^{n^{n}}}}} \right)$ queries, and the best known lower bound is $Ω(n^2)$; (iii) perfect allocations (a subset…

Here we demonstrate it based on a two-channel waveguide with compact lossy resonators. We realize imbalanced losses crucial for CPA EP by using active components to independently modulate the non-Hermiticity. The CPA EP experimentally manifests as full absorption at a unique real frequency and…

Sensitivity and transitivity for the induced maps on symmetric product suspensions of a topological space
Given a nondegenerate compact perfect and Hausdorff topological space $X$,$n\in \mathbb{N}$ and a function $f:X\rightarrow X$, we consider the $n$-fold symmetric product of $X$, $F_n(X)$ and the induced function $F_n(f):F_n(X)\rightarrow F_n(X)$. If $n\geq2$, we consider the $n$-fold symmetric product suspension of $X$, $SF_n(X)$ and the induced function$SF_n(f):SF_n(X)\rightarrow SF_n(X)$. In this paper, we study the relationships between the following statements: (1) $f\in \mathcal{M}$,(2) $F…

Decay of Interatomic Force Constants in the Reduced Hartree-Fock Model
We study the decay of the interatomic force constants (equivalently, the smoothness properties of the dynamical matrix) in perfect crystals both at finite electronic temperature, and for insulators at zero temperature, within the reduced Hartree-Fock approximation (also called Random Phase Approximation). At finite temperature the electrons are mobile, leading to exponential decay of the force constants. In insulators, there is incomplete screening, leading to an algebraic decay of dipole-dipol…

Casimir energy for $N$ constant conductivity $δ$-plates with a neural network perception
The Casimir energy for $N$ $δ$-function plates depends on the multiple scattering parameter $Δ$. This $N$-body interaction was distributed into interactions with nearest neighbour scattering and next-to-nearest neighbour scattering based on partitions of $N-1$ and its permutations. Implementing this methodology, we investigate the Casimir interaction for multiple plates with constant conductivity relatable to Graphene. We also study the Casimir energy between a perfect magnetic conductor and …

WWAggr: A Window Wasserstein-based Aggregation for Ensemble Change Point Detection
Change Point Detection (CPD) aims to identify moments of abrupt distribution shifts in data streams. Real-world high-dimensional CPD remains challenging due to data pattern complexity and violation of common assumptions. Resorting to standalone deep neural networks, the current state-of-the-art detectors have yet to achieve perfect quality. Concurrently, ensembling provides more robust solutions, boosting the performance. In this paper, we investigate ensembles of deep change point detectors an…

What a darling little girl. A.I., of course. Pixel-perfect!

Went to Indian motorcycles demo day yesterday to check out a few of the bikes. I am admittedly not a cruiser guy, but in the back of my mind I'd love to have a touring bike someday, or at least something that can eat up highway miles better than my vintage Yamaha. I love that bike, but it was geared for the 55mph speed limit of the day, so at 70mph the engine is turning at 4500rpm. There's no wind protection, and while I think the riding position is perfect for controlling a bike thr…

Strongly regular and strongly walk-regular graphs that admit perfect state transfer
We study perfect state transfer in Grover walks on two important classes of graphs: strongly regular graphs and strongly walk-regular graphs. The latter class is a generalization of the former. We first give a complete classification of strongly regular graphs that admit perfect state transfer. The only such graphs are the complete bipartite graph $K_{2,2}$ and the complete tripartite graph $K_{2,2,2}$. We then show that, if a genuine strongly walk-regular graph admits perfect state transfer, t…

(Btw.: Been running a t14s Gen6 Intel (Lunar Lake) for a few weeks now and its a really nice machine. Battery life is good [not Macbook levels but good], device stays cool, performance is great. Kernel support isn't perfect, sometimes after waking up the processor is stuck at its lowest scaling which correct itself after a bit but it seems to be a known bug that should be fixed soonish. Neat machine.)

On the methods of reduction of some types of Marczerwski-Burstin measurable functions to continuous functions on products of perfect sets
In this paper we provide product-wise generalizations of certain Marczewski-Burstin bases such as sets with (s)-property and completely Ramsey sets. For each of those we prove - as an analog of classical Luzin's and Eggleston's theorems that functions measurable with respect to those families can be reduced to continuous functions on a product of perfect sets. Moreover we also provide a way to reduce sequences of such functions to continuity, providing generalizations to Laver's extension of Ha…

On a Recursive Integer Sequence Implying the Nonexistence of Odd Perfect Numbers
We define a sequence of positive integers recursively, where each term is determined as follows: starting with a given positive integer, if the term is odd, the next is the sum of its positive divisors; if the term is even, the subsequent term is half the term. It is conjectured that the sequence eventually reaches one for all initial values. In this paper, we classify a family of integers for which this conjecture holds.

Perfect $1$-factorisations of $K_{11,11}$
A perfect $1$-factorisation of a graph is a decomposition of that graph into $1$-factors such that the union of any two $1$-factors is a Hamiltonian cycle. A Latin square of order $n$ is row-Hamiltonian if for every pair $(r,s)$ of distinct rows, the permutation mapping $r$ to $s$ has a single cycle of length $n$. We report the results of a computer enumeration of the perfect $1$-factorisations of the complete bipartite graph $K_{11,11}$. This also allows us to find all row-Hamiltonian Latin sq…

Perfect codes in quartic Cayley graphs of generalized dihedral groups
For a graph $Γ=(VΓ,EΓ)$, a subset $D$ of $VΓ$ is a perfect code in $Γ$ if every vertex of $Γ$ is dominated by exactly one vertex in $D$. In this paper, we classify all connected quartic Cayley graphs on generalized dihedral groups admitting a perfect code, and determine all perfect codes in such graphs.
