Non-linear bi-algebraic curves and surfaces in moduli spaces of Abelian differentials

open access: yesComptes Rendus. Mathématique, 2023
The strata of the moduli spaces of Abelian differentials are non-homogenous spaces carrying natural bi-algebraic structures. Partly inspired by the case of homogenous spaces carrying bi-algebraic structures (such as torii, Abelian varieties and Shimura ...

CM liftings of $K3$ surfaces over finite fields and their applications to the Tate conjecture

open access: yesForum of Mathematics, Sigma, 2021
We give applications of integral canonical models of orthogonal Shimura varieties and the Kuga-Satake morphism to the arithmetic of $K3$ surfaces over finite fields.

On an Isomorphism of Compactifications of Moduli Scheme of Vector Bundles

open access: yesМоделирование и анализ информационных систем, 2015
A morphism of the reduced Gieseker - Maruyama moduli functor (of semistable coherent torsion-free sheaves) on the surface to the reduced moduli functor of admissible semistable pairs with the same Hilbert polynomial, is constructed. It is shown that main

Family of Enneper Minimal Surfaces

open access: yesMathematics, 2018
We consider a family of higher degree Enneper minimal surface E m for positive integers m in the three-dimensional Euclidean space E 3 . We compute algebraic equation, degree and integral free representation of Enneper minimal surface for

Analytical surfaces for ship hulls

open access: yesRUDN Journal of Engineering Research, 2021
The choice of optimal shape of ship hull surface is one of the main problems of ship architects and designs. A choice of the form is based on empirical formulae or on intuition of designers.

A Physically Based Statistical Model With the Parameterized Topographic Effect for Predicting the Weakening of Tropical Cyclones After Landfall Over China

open access: yesGeophysical Research Letters, 2022
Accurate prediction of tropical cyclone (TC) intensity is important but challenging. In this study, a physically based algebraic decay model for predicting TC weakening after landfall over China is introduced, which assumes the TC weakening rate is ...

Correction of distortion in flattened representations of the cortical surface allows prediction of V1-V3 functional organization from anatomy. [PDF]

open access: yesPLoS Computational Biology, 2014
Several domains of neuroscience offer map-like models that link location on the cortical surface to properties of sensory representation. Within cortical visual areas V1, V2, and V3, algebraic transformations can relate position in the visual field to ...
