Weighted Linearization of Vector Fields via a Formal Moser Trick

Arthur Lei Qiu ยท 2026

Many well-known theorems establish sufficient criteria for linearizability of a vector field in terms of the eigenvalues of its linear approximation. By attaching weights to coordinates so that some dโ€ฆ

Reparameterization through Coverings and Topological Weight Priors

Maxim Beketov, Pavel Snopov ยท 2026

We generalise the reparameterization trick applied in variational autoencoders (VAEs) letting these have latent spaces of non-trivial topology - i.e. that of base manifolds covered with other ones, onโ€ฆ

Duality of Hamiltonian and Lagrangian formulations for integrable systems

Pierandrea Vergallo, Mats Vermeeren ยท 2026

We introduce the concept of Hamiltonian potential variables to map Hamiltonian operators into symplectic operators in a dual space. This generalises the classical trick of switching to a potential varโ€ฆ

All knots are trivial: a "proof" by sleight of hand

Raphael Appenzeller, Jose Pedro Quintanilha ยท 2026

We take a close look at a classical magic trick performed with a string, where a trivial knot is seemingly isotoped into a trefoil, and generalize it to a family of magic tricks for transforming the uโ€ฆ

RKHS method for computing Koopman-based Lyapunov functions

Francois-Gregoire Bierwart, Alexandre Mauroy ยท 2026

The Koopman operator is a powerful approach to global stability analysis of nonlinear systems, which provides a systematic procedure for Lyapunov function design. In this framework, Lyapunov functionsโ€ฆ

Ecohydrological Controls on Moist Convection and Long-Term Rainfall Feedback

Elizabeth Cultra, Jun Yin, Mark Bartlett, Amilcare Porporato ยท 2026

To elucidate how land surface state and soil moisture dynamics regulate moist convection, and how convective rainfall subsequently reshapes surface and root-zone hydrology, we develop a stochastic dynโ€ฆ

Non-isotopic surfaces in $T^4\#(S^2\times S^2)$: an example

Jianfeng Lin, Yue Wu ยท 2026

We prove that there exist infinitely many embedded tori with a common geometric dual in $T^4\#(S^2\times S^2)$ that are homotopic, diffeomorphic, but not isotopic to each other, even after arbitrary mโ€ฆ

The Geometry of Forgetting

Sambartha Ray Barman, Andrey Starenky, Sophia Bodnar, Nikhil Narasimhan, Ashwin Gopinath ยท 2026

Why do we forget? Why do we remember things that never happened? The conventional answer points to biological hardware. We propose a different one: geometry. Here we show that high-dimensional embeddiโ€ฆ

Learning Progressive Adaptation for Multi-Modal Tracking

He Wang, Tianyang Xu, Zhangyong Tang, Xiao-Jun Wu, Josef Kittler ยท 2026

Due to the limited availability of paired multi-modal data, multi-modal trackers are typically built by adopting pre-trained RGB models with parameter-efficient fine-tuning modules. However, these finโ€ฆ

Physical manifestation of replica symmetry breaking in a quantum glass of bosons with off-diagonal disorder

Anna M. Piekarska, Tadeusz K. Kopec ยท 2026

Glassiness occurs when disorder and frustration cause local degrees of freedom to freeze despite the lack of long-range order. In systems of interacting bosons, such glassiness may involve a purely quโ€ฆ
