On relations between one-dimensional quantum and two-dimensional classical spin systems [PDF]

open access: yes, 2015
We exploit mappings between quantum and classical systems in order to obtain a class of two-dimensional classical systems with critical properties equivalent to those of the class of one-dimensional quantum systems discussed in a companion paper (J ...

Logarithmic matrix transformations into Gw

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
We introduced the logarithmic matrix Lt and studied it as mappings into ℓ and G in 1998 and 2000, respectively. In this paper, we study Lt as mappings into Gw.

Convex (α, β)-Generalized Contraction and Its Applications in Matrix Equations

open access: yesAxioms, 2023
This paper investigates the existence and convergence of solutions for linear and nonlinear matrix equations. This study explores the potential of convex (α,β)-generalized contraction mappings in geodesic spaces, ensuring the existence of solutions for ...

The Perron-Frobenius Theorem for Multihomogeneous Mappings [PDF]

open access: yesSIAM Journal on Matrix Analysis and Applications, 2017
The Perron-Frobenius theory for nonnegative matrices has been generalized to order-preserving homogeneous mappings on a cone and more recently to nonnegative multilinear forms.

Fixed Point Results for C-Contractive Mappings in Generalized Metric Spaces with a Graph

open access: yesJournal of Function Spaces, 2021
In this paper, we establish fixed point theorems for Chatterjea contraction mappings on a generalized metric space endowed with a graph. Our results extend, generalize, and improve many of existing theorems in the literature.

Multidimensional Toda type systems [PDF]

open access: yes, 1996
On the base of Lie algebraic and differential geometry methods, a wide class of multidimensional nonlinear systems is obtained, and the integration scheme for such equations is proposed.Comment: 29 pages, LaTeX ...

About the role of constraints in the linear relaxational behaviour of thermodynamic systems [PDF]

open access: yes, 1978
A formalism is presented by which the linear relaxational behaviour of thermodynamic systems can be described. Instead of using the concept of internal variables of state a set of so-called constraint equations is introduced.

Fixed Point Results for Orthogonal Z-Contraction Mappings in O-Complete Metric Spaces

open access: yes, 2020
In this paper, we introduce the notion of orthogonal Z-contraction mappings and prove fixed point theorems for such contraction mappings in orthogonally metric spaces, which are generalizations of fixed point results for Z-contraction mappings in metric ...
