Heat as a gauge connection
arXiv:2503.08753v2 Announce Type: replace-cross Abstract: We show that heat defines a gauge connection on a line bundle over work configurations. Vanishing curvature is equivalent to the local existence of entropy and temperature functions such that heat can be expressed as $TdS$. A conjecture of Jauch, that entropy an...

Realising all countable groups as quasi-isometry groups
arXiv:2601.06261v1 Announce Type: new Abstract: Given any countable group $G$, we construct uncountably many quasi-isometry classes of proper geodesic metric spaces with quasi-isometry group isomorphic to $G$. Moreover, if the group $G$ is a hyperbolic group, the spaces we construct are hyperbolic metric spaces. We mak...

A characterisation of probabilistic metrizability for approach spaces
arXiv:2601.06269v1 Announce Type: new Abstract: Characterisations of metrizable topological spaces or metrizable uniform spaces are well known. A natural counterpart to being metrizable for topological spaces can be expressed in terms of probabilistic metrizability for approach spaces. The notion of a probabilistic met...

Minimality of free-boundary axial hyperplanes in high dimensional circular cones via calibration
arXiv:2601.06601v1 Announce Type: new Abstract: Consider an $(n+1)$-dimensional circular cone. Using a calibration argument, we prove that if $n \geq 4$ and the aperture of the cone is sufficiently large, the intersection of the cone with an axial hyperplane is area-minimizing with respect to free-boundary variations i...

Families of Toeplitz operators, family index and deformation quantization
arXiv:2601.06619v1 Announce Type: new Abstract: Given a contact fibration, we construct smooth families of Szeg\"o projections on the fibers. This allows us to define smooth families of Toeplitz operators. We apply these operators to construct a deformation quantization of prequantizable symplectic fibrations, recoveri...

Inexact DC Algorithms in Hilbert Spaces with Applications to PDE-Constrained Optimization
arXiv:2601.06622v1 Announce Type: new Abstract: In this paper, we design and apply novel inexact adaptive algorithms to deal with minimizing difference-of-convex (DC) functions in Hilbert spaces. We first introduce I-ADCA, an inexact adaptive counterpart of the well-recognized DCA (difference-of-convex algorithm), that...

Khintchin conjecture and related topics
arXiv:2601.06626v1 Announce Type: new Abstract: Motivated by Khintchin's 1923 conjecture, refuted by Marstrand in 1970, we study the Khintchin class of functions associated to a given increasing sequence of integers. When the Khintchin class contains L^p(\mathbb{T}), we call the sequence a L^p-Khintchin sequence. We es...
