On Generalized Sehgal–Guseman-Like Contractions and Their Fixed-Point Results with Applications to Nonlinear Fractional Differential Equations and Boundary Value Problems for Homogeneous Transverse Bars

open access: yesMathematics
The goal of this study is to describe the class of modified Sehgal–Guseman-like contraction mappings and set up some fixed-point results in S-metric spaces. The class of generalized Sehgal–Guseman-like contraction mappings contains enhancements of Banach

On Surfaces of Exceptional Lorentzian Lie Groups with a Four-Dimensional Isometry Group

open access: yesMathematics
In total, geodesic surfaces and their generalizations, namely totally umbilical and parallel surfaces, are well-known topics in Submanifold Theory and have been intensively studied in three-dimensional ambient spaces, both Riemannian and Lorentzian.

Well-posed initial-boundary value problems for the Zakharov-Kuznetsov equation

open access: yesElectronic Journal of Differential Equations, 2008
This paper deals with non-homogeneous initial-boundary value problems for the Zakharov-Kuznetsov equation, which is one of the variants of multidimensional generalizations of the Korteweg-de Vries equation.

Fractional Paley-Wiener and Bernstein spaces [PDF]

open access: yes, 2021
We introduce and study a family of spaces of entire functions in one variable that generalise the classical Paley-Wiener and Bernstein spaces. Namely, we consider entire functions of exponential type a whose restriction to the real line belongs to the ...

Holomorphic Function Spaces on Homogeneous Siegel Domains

open access: yes, 2022
We study several connected problems of holomorphic function spaces on homogeneous Siegel domains. The main object of our study concerns weighted mixed norm Bergman spaces on homogeneous Siegel domains of type II.

Laurent polynomial Landau-Ginzburg models for cominuscule homogeneous spaces and mirror symmetry for the exceptional family [PDF]

open access: yes, 2021
This thesis considers mirror symmetry for the small quantum cohomology of cominuscule homogeneous spaces. We present two main results: Firstly, in Theorem 2.2.7, we present a type-independent Laurent polynomial expression for Rietsch's Lie-theoretic ...

Submanifolds with curvature normals of constant length and the Gauss map [PDF]

open access: yes, 2004
We show that a submanifold with curvature normal of constant length has constant principal curvatures under suitable global hypothesis.

On the dynamics of sup-norm non-expansive maps [PDF]

open access: yes, 2005
We present several results for the periods of periodic points of sup-norm non-expansive maps. In particular, we show that the period of each periodic point of a sup-norm non-expansive map $f\colon M\to M$, where $M\subset \mathbb{R}^n$, is at most ...

Killing-Yano 2-forms on homogeneous spaces [PDF]

open access: yes, 2018
Riemannian manifolds carrying skew (1, 1)-tensors satisfying the Killing-Yano equation are natural generalizations of nearly Kähler manifolds. In this article we investigate the existence of invariant solutions to the Killing-Yano equation on homogeneous

On $m$-point homogeneous polytopes in Euclidean spaces

open access: yes, 2022
This paper is devoted to the study the $m$-point homogeneity property and the point homogeneity degree for finite metric spaces. Since the vertex sets of regular polytopes, as well as of some their generalizations, are homogeneous, we pay much attention ...
