Orthosymplectic Chern-Simons Matter Theories: Global Forms, Dualities, and Vacua
A magnetic quiver framework is proposed for studying maximal branches of 3d orthosymplectic Chern-Simons matter theories with $\mathcal{N} \geq 3$ supersymmetry, arising from Type IIB brane setups with O3 planes. These branches are extracted via brane moves, yielding orthosymplectic $\mathcal{N}=4$ magnetic quivers whose Coulomb branches match the moduli spaces of interest. Global gauge group data, inaccessible from brane configurations alone, are determined through supersymmetric indices, Hilb…

Quivers with Involutions and Shifted Twisted Yangians via Coulomb Branches
To a quiver with involution, we study the Coulomb branch of the 3d $\mathcal{N} = 4$ involution-fixed part of the quiver gauge theory. We show that there is an algebra homomorphism from the corresponding shifted twisted Yangian to the quantized Coulomb branch algebra. This gives a new instance of 3D mirror symmetries.

How to Push and Pull from GitHub Pull Request Branches
GitHub has the cool feature where while opening a pull request one can allow the maintainers to push changes to that branch. This is a lot more ergonomic than suggesting larger-scale edits in the insufferably slow GitHub web UI. But it does require setting up remotes and upstream branches correctly.

Global Hopf bifurcation and connected components in a delayed predator-prey model
We study the dynamics of a delayed predator-prey system with Holling type II functional response, focusing on the interplay between time delay and carrying capacity. Using local and global Hopf bifurcation theory, we establish the existence of sequences of bifurcations as the delay parameter varies, and prove that the connected components of global Hopf branches are nested under suitable conditions. A novel contribution is to show that the classical limit cycle of the non-delayed system belongs…

Periodic orbits underlying spatiotemporal chaos in the Lugiato-Lefever model
We obtain and investigate theoretically a broad family of stable and unstable time-periodic orbits-oscillating Turing rolls (OTR)-in the Lugiato-Lefever model of optical cavities. Using the dynamical systems tools developed in fluid dynamics, we access the OTR solution branches in parameter space and elucidate their bifurcation structure. By tracking these exact invariant solutions deeply into the chaotic region of the modulation instability, we connect the main dynamical regimes of the Lugiato…

AI-Assisted Geometric Analysis of Cultured Neuronal Networks: Parallels with the Cosmic Web
Building on evidence of structural parallels between brain networks and the cosmic web [1], we apply AI-based geometric analysis to cultured neuronal networks. Isolated neurons self-organize into dendritic lattices shaped by reproducible wiring rules. These lattices show non-random features-frequent dendritic convergence, hub nodes, small-world connectivity, and large voids. Synaptic contacts cluster and strengthen at hubs. Strikingly, these properties mirror the cosmic web: dendritic branches …

Real-time image classification on resource-constrained platforms demands inference methods that balance accuracy with strict latency and power budgets.

However, conventional training of early exits introduces a covariance shift: downstream branches are trained on full datasets, while at inference they pro…

In this framework, a broad class of Crump-Mode-Jagers processes can be constructed as (a)symmetric Sevast'yanov processes, which count the branches of the tree. Analogous definitions yield reduced (a)symmetric Sevast'yanov processes, which restrict attention to branches that lead to extant progeny. We …

Generating such invariants is a crucial task in loop analysis, but it is undecidable in the general case. Recently, an alternative approach to this problem has emerged, focusing on synthesizing loops from invariants. However, existin…

K-theoretic Hikita conjecture for quiver gauge theories
We study variants of Hikita conjecture for Nakajima quiver varieties and corresponding Coulomb branches. First, we derive the equivariant version of the conjecture from the non-equivariant one for a set of gauge theories. Second, we suggest a variant of the conjecture, with K-theoretic Coulomb branches involved. We show that this version follows from the usual (homological) one for a set of theories. We apply this result to prove the conjecture in finite ADE types. In the course of the proof, w…

Dissociation of bulk and entanglement phase transitions in the Haldane phase
We revisit the momentum-resolved entanglement spectrum (ES) of the spin-1/2 ladder in the Haldane phase, long believed to exhibit a des Cloizeaux-Pearson (dCP)-type $\sin|k|$ dispersion. Using exact diagonalization up to 40 spins, we resolve two distinct branches at $k=0$ and $k=π$, which were previously interpreted as a single smooth mode due to SU(2) degeneracy and limited resolution. Breaking SU(2) symmetry via XXZ anisotropy opens a spin or neutral gap at $k=π$, depending on the…

Slant sums of quiver gauge theories
We define a notion of slant sum of quiver gauge theories, a type of surgery on the underlying quiver. Under some mild assumptions, we relate torus fixed points on the corresponding Higgs branches, which are Nakajima quiver varieties. Then we prove a formula relating the quasimap vertex functions before and after a slant sum, which is a type of ``branching rule" for vertex functions. Our construction is motivated by a conjecture, which we make here, for the factorization of the vertex function…

One more photo stop that we did after quite a rain pour in the #schwarzwald.
We came up this path when I turned around and saw the sun beams through the canopy. At first I was really stunned to be honest as I hardly *ever* see such scenes!
Strangely I took ways less photos than might have been appropriate, but those two I found worth sharing.
Some more story about them:

This is another photo I was able to take in the #schwarzwald . You might have seen it in my recent blog post. But I wanted to share it here as well.
What really surprises me is how it looked on location vs here now. On location there was a lot of forest around, lots of clutter. It was a challenge to find this view through the foreground so that I could single out this gem of a tree but…

My take for #FootpathFriday from our vacation in the #schwarzwald / #blackforest Iast year.
#hiking

It's been a day with a lot of input. The absolute opposite of this where I was completely alone.

Hey all, there are some photos from a hike in the #schwarzwald
Actually we thought that it would just take us less than an hour - but it wasn't simply a straight walk :-D
It was raining from time to time - which was indeed pretty cool. A) there was noone around except us and B) the colors were often just insane. Fully saturated green, the brown from the wood - and sometimes…

Good morning!
Here are some photos from the #Mummelsee in the #Schwarzwald . We wanted to visit it last year already but somehow just managed to go there this time.
The lake itself is scenic and beautiful. But definitely a "hot spot". Luckily we were there at a day/time w…

Last photos from that day in the #schwarzwald . We were pretty surprised when we came to the part shown in the last photo. The #moss was so thick there - like a real carpet! I've never seen such before. I found it pretty hard to get a photo that pays the situation justice. I hope it works for …
