Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic
Communications on Pure and Applied Mathematics, Volume 79, Issue 8, Page 1973-2102, August 2026.ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Weak, Strong and Mixed Extensions of Relations to Spaces of Ultrafilters
Mathematical Logic Quarterly, Volume 72, Issue 3, August 2026.ABSTRACT The use of nonstandard methods to characterize properties of weak, strong and mixed extensions of congruences to ultrafilters has been the main topic of several recent papers, focused mostly on congruences and divisions. We show that similar methods can be used to extend these characterizations to arbitrary relations and their interplay.

The Glass Transition: A Topological Perspective
EntropyResorting to microcanonical ensemble Monte Carlo simulations, we study the geometric 1 and topological properties of the state space of a model of network glass-former. This model, a 2 Lennard-Jones binary mixture, does not crystallize due to frustration.

Relationships among Various Chaos for Linear Semiflows Indexed with Complex Sectors
MathematicsIn this paper, we investigate the relationships among point transitivity, topological transitivity, Li–Yorke chaos, and the existence of irregular vectors for a linear semiflow {Tt}t∈Δ indexed with a complex sector.

Inducing Coverings on Hilbert Schemes
Mathematische Nachrichten, Volume 299, Issue 8, Page 2177-2190, August 2026.ABSTRACT We find an explicit geometric description of all coverings of Hilb2(Σ)$\operatorname{Hilb}^{2}(\Sigma)$ when Σ$\Sigma$ is a normal, complex, quasi‐projective surface with finite fundamental group. We then apply this construction to show that if Σ$\Sigma$ is an irreducible symplectic surface then Hilb2(Σ)$\operatorname{Hilb}^{2}(\Sigma)$ is an ...

An Improved Chaotic Motion Path Planner for Autonomous Mobile Robots Based on a Logistic Map
International Journal of Advanced Robotic Systems, 2013 This paper presents a chaotic motion path planner based on a Logistic Map (SCLCP) for an autonomous mobile robot to cover an unknown terrain randomly, namely entirely, unpredictably and evenly.

Dynamic Reconfiguration of Functional Topology in Human Brain Networks: From Resting to Task States
Neural Plasticity, 2020 Task demands evoke an intrinsic functional network and flexibly engage multiple distributed networks. However, it is unclear how functional topologies dynamically reconfigure during task performance. Here, we selected the resting- and task-state (emotion

Asymmetric Results About Graph Homomorphisms
Random Structures &Algorithms, Volume 69, Issue 1, August 2026.ABSTRACT Many important results in extremal graph theory can be roughly summarized as “if a triangle‐free graph G$$ G $$ has certain properties, then it has a homomorphism to a triangle‐free graph Γ$$ \Gamma $$ of bounded size.” For example, bounds on homomorphism thresholds give such a statement if G$$ G $$ has sufficiently high minimum degree, and ...

Long Run Non‐Transitivity of Win Ratio and How to Rule It Out
Statistics in Medicine, Volume 45, Issue 18-19, August 2026.ABSTRACT The win ratio (WR) has emerged as an increasingly used method for analyzing composite endpoints in randomized controlled trials (RCTs). Its growing popularity stems from its ability to accommodate a hierarchy of event types within a composite primary endpoint in an RCT.
