ADMITTING CENTER MAPS ON MULTIPLICATIVE METRIC SPACE [PDF]

Journal of Algebraic Systems, 2020
‎In this work‎, ‎we investigate admitting center map on multiplicative metric space‎ ‎and establish some fixed point theorems for such maps‎. ‎We modify the Banach contraction principle and‎ ‎the Caristi's fixed point theorem for M-contraction ...

Multivalued SK-contractions with respect to b-generalized pseudodistances [PDF]

, 2015
A new class of multivalued non-self-mappings, called SK-contractions with respect to b-generalized pseudodistances, is introduced and used to investigate the existence of best proximity points by using an appropriate geometric property. Some new fixed

Further generalizations of the Banach contraction principle [PDF]

Journal of Inequalities and Applications, 2014
AbstractWe establish a new fixed point theorem in the setting of Branciari metric spaces. The obtained result is an extension of the recent fixed point theorem established in Jleli and Samet (J. Inequal. Appl. 2014:38, 2014).

Generalized Ulam-Hyers Stability, Well-Posedness, and Limit Shadowing of Fixed Point Problems for α-β-Contraction Mapping in Metric Spaces

The Scientific World Journal, 2014
We study the generalized Ulam-Hyers stability, the well-posedness, and the limit shadowing of the fixed point problem for new type of generalized contraction mapping, the so-called α-β-contraction mapping.

On the fractional partial integro-differential equations of mixed type with non-instantaneous impulses

Boundary Value Problems, 2020
In this paper, we consider the initial boundary value problem for a class of nonlinear fractional partial integro-differential equations of mixed type with non-instantaneous impulses in Banach spaces.

Extensions of the Banach contraction principle in multiplicative metric spaces [PDF]

Vojnotehnicki glasnik, 2017
In this paper, we have proven several generalizations of the Banach contraction principle for multiplicative metric spaces. We have also derived the Cantor intersection theorem in the setup of multiplicative metric spaces. Non-trivial supporting examples are also given.

New Fixed Point Theorems for θ−ω−Contraction on λ,μ-Generalized Metric Spaces

Journal of Function Spaces, 2023
In this paper, we consider a new extension of the Banach contraction principle, which is called the θ−ω−contraction inspired by the concept of θ−contraction in λ,μ-generalized metric spaces and to study the existence and uniqueness of fixed point for the

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

New Generalised Semi‐Analytical Approach for the Multidimensional Nonlinear Collisional Fragmentation Equations

International Journal for Numerical Methods in Fluids, EarlyView.
This work aims to develop a generalised and efficient semi‐analytical method that combines the Laplace decomposition method with Pade approximation (LDMPA) to solve multidimensional nonlinear integro‐partial differential equation. For a one‐dimension case, explicit (closed‐form) solutions for the number density functions are derived for the first time.
