Deformed Aeppli cohomology: canonical deformations and jumping formulas
Given a complex analytic family of complex manifolds, we consider canonical Aeppli deformations of $(p,q)$-forms and study its relations to the varying of dimension of the deformed Aeppli cohomology $\dim H^{\bullet,\bullet}_{Aϕ(t)}(X)$. In particular, we prove the jumping formula for the deformed Aeppli cohomology $H^{\bullet,\bullet}_{Aϕ(t)}(X)$. As a direct consequence, $\dim H^{p,q}_{Aϕ(t)}(X)$ remains constant iff the Bott-Chern deformations of $(n-p,n-q)$-forms and the Aeppli deformati…

Theoretical Learning Performance of Graph Neural Networks: The Impact of Jumping Connections and Layer-wise Sparsification
Jumping connections enable Graph Convolutional Networks (GCNs) to overcome over-smoothing, while graph sparsification reduces computational demands by selecting a sub-matrix of the graph adjacency matrix during neighborhood aggregation. Learning GCNs with graph sparsification has shown empirical success across various applications, but a theoretical understanding of the generalization guarantees remains limited, with existing analyses ignoring either graph sparsification or jumping connections.…

@… while I agree with most of your points I do need to note that LLM is amazing as a booster when I don't even know what I don't know. Like jumping to some new framework with no clue where to even begin with the docs.

Hello !
There’s a lot of TL jumping since beta 3. Either while inside the app or when going away/back

Kudos to @… for jumping on the hotfix so quickly for this instance. No idea when, or if, that guy sleeps 😄

Algebraic Zhou valuations
In this paper, we generalize Zhou valuations, originally defined on complex domains, to the framework of general schemes. We demonstrate that an algebraic version of the Jonsson--Mustaţă conjecture is equivalent to the statement that every Zhou valuation is quasi-monomial. By introducing a mixed version of jumping numbers and Tian functions associated with valuations, we obtain characterizations of a valuation being a Zhou valuation or computing some jumping number using the Tian functions.

A Note on Reconfiguration Graphs of Cliques
In a reconfiguration setting, each clique of a graph $G$ is viewed as a set of tokens placed on vertices of $G$ such that no vertex has more than one token and any two tokens are adjacent. Additionally, three well-known reconfiguration rules have been studied in the literature: Token Jumping ($\mathsf{TJ}$, which involves moving a token to any unoccupied vertex), Token Sliding ($\mathsf{TS}$, which involves moving a token to an adjacent unoccupied vertex), and Token Addition/Removal ($\mathsf{T…

Jumping for diffusion in random metastable systems
Random metastability occurs when an externally forced or noisy system possesses more than one state of apparent equilibrium. This work investigates fluctuations in a class of random dynamical systems, arising from randomly perturbing a piecewise smooth expanding interval map with more than one invariant subinterval. Upon perturbation, this invariance is destroyed, allowing trajectories to switch between subintervals, giving rise to metastable behaviour. We show that the distributions of jumps o…

We need to stop reasoning about AI like this. Every time it can do something amazing it's "well that's just because its training data is so big, everything is bound to be in there."
Then, when it shows some limitation, it's "Well that's because it must not be in the training data".
It can show a shark jumping out of the moon through a computer screen. It can generate stuff that's not in the data. Also, hands counting down are obviously in t…

Two Dimensional Silver Dollar Game
We define a variant of the two-dimensional Silver Dollar game. Two coins are placed on a chessboard of unbounded size, and two players take turns choosing one of the coins and moving it. Coins are to be moved to the left or upward vertically as far as desired. If a coin is dropped off the board, players cannot use this coin. Jumping a coin over another coin or on another coin is illegal. We add another operation: moving a coin and pushing another coin. For non-negative integers w,x,y,z, we deno…

Neuralocks: Real-Time Dynamic Neural Hair Simulation
Real-time hair simulation is a vital component in creating believable virtual avatars, as it provides a sense of immersion and authenticity. The dynamic behavior of hair, such as bouncing or swaying in response to character movements like jumping or walking, plays a significant role in enhancing the overall realism and engagement of virtual experiences. Current methods for simulating hair have been constrained by two primary approaches: highly optimized physics-based systems and neural methods.…

Thinking Hard About Physics Before Calculating: An Example from Pendulum Physics
This paper aims to show how to guide students with a familiar example to extract as much physics as possible before jumping into mathematical calculation. The period for a physical pendulum made up of a uniform rod is changed by attaching a piece of putty on it. The period for the combined system depends on the location of the putty. Simple reasoning without calculation shows that there are two locations for the putty that do not change the period of the physical pendulum: the axis and the cent…

Saltatory targeting strategy in rock-paper-scissors models
We explore how strategic leaps alter the classic rock-paper-scissors dynamics in spatially structured populations. In our model, individuals can expend energy reserves to jump toward regions with a high density of individuals of the species they dominate in the spatial game. This enables them to eliminate the target organisms and gain new territory, promoting species proliferation. Through stochastic, lattice-based simulations, we show that even when the energy allocated to jumping, as opposed …
