Metric SYZ conjecture and non-archimedean geometry [PDF]
arXiv, 2020 We show that assuming a conjecture in non-archimedean geometry, then a metric formulation of the SYZ conjecture can be proved in large generality.

Sub-Riemannian Geometry in Image Processing and Modeling of the Human Visual System
Nelineinaya Dinamika, 2019 This paper summarizes results of a sequence of works related to usage of sub-Riemannian (SR) geometry in image processing and modeling of the human visual system. In recent research in psychology of vision (J. Petitot, G.Citti, A.

On a Dirichlet problem related to anisotropic fluid flow in bidisperse porous media
Mathematical Methods in the Applied Sciences, Volume 48, Issue 3, Page 3652-3669, February 2025.This paper is concerned with the study of a Dirichlet boundary value problem for a system of two coupled anisotropic Darcy–Forchheimer–Brinkman equations on a bounded Lipschitz domain in ℝn(n=2,3)$$ {\mathrm{\mathbb{R}}}^n\left(n=2,3\right) $$. Using variational methods and fixed point techniques, we obtain a well‐posedness result in L2$

Noncommutative spectral geometry of Riemannian foliations [PDF]
arXiv, 1997 We construct spectral triples in a sense of noncommutative differential geometry, associated with a Riemannian foliation on a compact manifold, and describe its dimension spectrum.

Hermite solution for a new fractional inverse differential problem
Mathematical Methods in the Applied Sciences, Volume 48, Issue 3, Page 3811-3824, February 2025.Mathematics, mathematical modeling of real systems, and mathematical and computer methodologies aimed at the qualitative and quantitative study of real physical systems interact in a nontrivial way. This work aims to examine a new class of inverse problems for a fractional partial differential equation with order fractional 0<ρ≤1$$ 0<\rho \le 1 ...

The sphere and the cut locus at a tangency point in two-dimensional almost-Riemannian geometry
, 2010 We study the tangential case in 2-dimensional almost-Riemannian geometry. We analyse the connection with the Martinet case in sub-Riemannian geometry. We compute estimations of the exponential map which allow us to describe the conjugate locus and the ...

Galois theory and projective geometry [PDF]
arXiv, 2011 We explore connections between birational anabelian geometry and abstract projective geometry. One of the applications is a proof of a version of the birational section conjecture.
