Fibration by non-smooth projective curves of arithmetic genus two in characteristic two
Alejandro Simarra Cañate, Karl-Otto Stöhr
Looking in positive characteristic for failures of the Bertini-Sard theorem, we determine, up to birational equivalence, the separable proper morphisms of smooth algebraic varietie…
Halfspace type Theorems for Self-Shrinkers
Marcos P. Cavalcante, Jose M. Espinar
In this short paper we extend the classical Hoffman-Meeks Halfspace Theorem to self-shrinkers, that is: "Let be a hyperplane passing through the origin. The only properly imme…
Extremal problems in de Branges spaces: the case of truncated and odd functions
Emanuel Carneiro, Felipe Gonçalves
In this paper we find extremal one-sided approximations of exponential type for a class of truncated and odd functions with a certain exponential subordination. These approximation…
Diffusion for chaotic plane sections of 3-periodic surfaces
Artur Avila, Pascal Hubert, Alexandra Skripchenko
We study chaotic plane sections of some particular family of triply periodic surfaces. The question about possible behavior of such sections was posed by S. P. Novikov. We prove so…
Canonical extension of submanifolds and foliations in noncompact symmetric spaces
Miguel Dominguez-Vazquez
We propose a method to extend submanifolds, singular Riemannian foliations and isometric actions from a boundary component of a noncompact symmetric space to the whole space. This…
The geometric semantics of algebraic quantum mechanics
John Alex Cruz Morales, Boris Zilber
In this paper we will present an ongoing project which aims to use model theory as a suitable mathematical setting for studying the formalism of quantum mechanics. We will argue th…
