Some fundamental problems in global Finsler geometry [PDF]

open access: yesAUT Journal of Mathematics and Computing, 2021
The geometry and analysis on Finsler manifolds is a very important part of Finsler geometry. In this survey article, we introduce some important and fundamental topics in global Finsler geometry and discuss the related properties and the relationships in

Some recent developments on the Steklov eigenvalue problem [PDF]

open access: yesRevista Matemática Complutense, 2022
The Steklov eigenvalue problem, first introduced over 125 years ago, has seen a surge of interest in the past few decades. This article is a tour of some of the recent developments linking the Steklov eigenvalues and eigenfunctions of compact Riemannian ...

Evolution for First Eigenvalue of LT,f on an Evolving Riemannian Manifold

open access: yesMathematics, 2022
In this paper, evolution formulas for the first non-zero eigenvalue of the operator LT,f on a weighted closed Riemannian manifold along the Ricci flow as well as along the Yamabe flow are formulated.

The Square of Some Generalized Hamming Graphs

open access: yesMathematics, 2023
In this paper, we study the square of generalized Hamming graphs by the properties of abelian groups, and characterize some isomorphisms between the square of generalized Hamming graphs and the non-complete extended p-sum of complete graphs.

Construction and Application of Discrete-Time-Domain Framework -based Power-Grid State Space

open access: yesZhongguo dianli, 2022
To obtain the eigenvalue more efficiently and conveniently, a discrete time domain model (DTDM) based state space construction method is proposed for power grids, and the stability criterion of is presented.

Approximate Diagonal Integral Representations and Eigenmeasures for Lipschitz Operators on Banach Spaces

open access: yesMathematics, 2022
A new stochastic approach for the approximation of (nonlinear) Lipschitz operators in normed spaces by their eigenvectors is shown. Different ways of providing integral representations for these approximations are proposed, depending on the properties of

A variational eigenvalue solver on a photonic quantum processor [PDF]

open access: yesNature Communications, 2013
Quantum computers promise to efficiently solve important problems that are intractable on a conventional computer. For quantum systems, where the physical dimension grows exponentially, finding the eigenvalues of certain operators is one such intractable

Properties of Entropy-Based Topological Measures of Fullerenes

open access: yesMathematics, 2020
A fullerene is a cubic three-connected graph whose faces are entirely composed of pentagons and hexagons. Entropy applied to graphs is one of the significant approaches to measuring the complexity of relational structures.

Global bifurcation of sign-changing radial solutions of elliptic equations of order 2m in annular domains

open access: yesAIMS Mathematics, 2020
In this paper we study the global bifurcation of sign-changing radial solutions for some semilinear elliptic problems of order 2m in an annulus with Dirichlet boundary conditions.
