Generalized Dynamical Ordering and Topological Entropy in the Henon Map

Progress of Theoretical Physics, 2005
Summary: Under area- and orientation-preserving maps, the images of the symmetry axes accumulate at the unstable manifold of a saddle fixed point \(P\), while their inverse images accumulate at the stable manifold of \(P\). Before or after the tangency of these stable and unstable manifolds, four types of generalized dynamical ordering are derived ...

Community-entropy Based Graph Structure Learning for Topology-imbalance

IEEE International Conference on Acoustics, Speech, and Signal Processing
Graph Structure Learning (GSL) recently has attracted considerable attentions. Existing GSL methods assume that nodes with high attribute similarity belong to the same class.

Spectral Guardrails for Agents in the Wild: Detecting Tool Use Hallucinations via Attention Topology

arXiv.org
Deploying autonomous agents in the wild requires reliable safeguards against tool use failures. We propose a training free guardrail based on spectral analysis of attention topology that complements supervised approaches.

Black ring entropy from the Weyl tensor

Frontiers of Physics, 2017
A black ring is an asymptotically flat vacuum solution of the n-dimensional Einstein equations with an event horizon of topology S1 x Sn-3. In this study, a connection between the black ring entropy and the Weyl tensor Cμvλρ is explored by interpreting ...

On the use of local maximum entropy approximants for Cahn–Hilliard phase-field models in 2D domains and on surfaces

Computer Methods in Applied Mechanics and Engineering, 2019
We apply a local maximum entropy (LME) approximation scheme to the fourth order phase-field model for the traditional Cahn–Hilliard theory. The discretization of the Cahn–Hilliard equation by Galerkin method requires at least C 1 -continuous basis ...
