Heterogeneous Multi-Agent Tracking with Cellular Sheaves

Published:Dec 31, 2025 14:29
1 min read
ArXiv

Analysis

This paper addresses the challenging problem of multi-agent target tracking with heterogeneous agents and nonlinear dynamics, which is difficult for traditional graph-based methods. It introduces cellular sheaves, a generalization of graph theory, to model these complex systems. The key contribution is extending sheaf theory to non-cooperative target tracking, formulating it as a harmonic extension problem and developing a decentralized control law with guaranteed convergence. This is significant because it provides a new mathematical framework for tackling a complex problem in robotics and control.
Reference

“The tracking of multiple, unknown targets is formulated as a harmonic extension problem on a cellular sheaf, accommodating nonlinear dynamics and external disturbances for all agents.”

Period Map and Derived Invariants in Algebraic Geometry

Published:Dec 30, 2025 16:58
1 min read
ArXiv

Analysis

This paper investigates the relationship between deformations of a scheme and its associated derived category of quasi-coherent sheaves. It identifies the tangent map with the dual HKR map and explores derived invariance properties of liftability and the deformation functor. The results contribute to understanding the interplay between commutative and noncommutative geometry and have implications for derived algebraic geometry.
Reference

“The paper identifies the tangent map with the dual HKR map and proves liftability along square-zero extensions to be a derived invariant.”

Admissible HYM Metrics and MY Equality on Klt Varieties

Published:Dec 30, 2025 11:47
1 min read
ArXiv

Analysis

This paper presents three key results in the realm of complex geometry, specifically focusing on Kähler-Einstein (KE) varieties and vector bundles. The first result establishes the existence of admissible Hermitian-Yang-Mills (HYM) metrics on slope-stable reflexive sheaves over log terminal KE varieties. The second result connects the Miyaoka-Yau (MY) equality for K-stable varieties with big anti-canonical divisors to the existence of quasi-étale covers from projective space. The third result provides a counterexample regarding semistability of vector bundles, demonstrating that semistability with respect to a nef and big line bundle does not necessarily imply semistability with respect to ample line bundles. These results contribute to the understanding of stability conditions and metric properties in complex geometry.
Reference

“If a reflexive sheaf $\mathcal{E}$ on a log terminal Kähler-Einstein variety $(X,ω)$ is slope stable with respect to a singular Kähler-Einstein metric $ω$, then $\mathcal{E}$ admits an $ω$-admissible Hermitian-Yang-Mills metric.”
