Convexity and boundedness relaxation for fixed point theorems in modular spaces
Applied General Topology, 2021 Although fixed point theorems in modular spaces have remarkably applied to a wide variety of mathematical problems, these theorems strongly depend on some assumptions which often do not hold in practice or can lead to their reformulations as particular ...

Fixed point results for Suzuki‐type Σ‐contractions via simulation functions in modular b‐metric spaces [PDF]
Mathematical Methods in the Applied Sciences, 2020 This study aims to introduce Suzuki‐type Σ‐contraction mappings with simulation functions in the framework of modular b‐metric spaces. Some coincidence and common fixed point results are obtained for four mappings with the weak compatibility property. Outcomes are the extensions and improvements of the existing literature.

Fundamental Journal of Mathematics and Applications, 2022 This article aims to specify a new $C-$class function endowed with altering distance and ultra altering distance function via generalized $\Xi -$contraction, which is called the $\mathcal{G}\left( {\Sigma ,\vartheta ,\Xi } \right) - $contraction in modular $b-$metric spaces.

On generalized Suzuki-Proinov type (α,Z*E)−contractions in modular b−metric spaces
Filomat, 2023 This paper?s objective is to put forward anewkind of E?type contraction, which includes rational expression, by considering Proinov type functions and CG?simulation functions. This type of contraction is termed as a Suzuki-Proinov type generalized (?,Z* E)?contraction mapping.

Partition Functions, Duality, and the Tube Metric [PDF]
, 1997 The partition function of type IIA and B strings on R^6xK3, in the T^4/Z_2 orbifold limit, is explicitly computed as a modular invariant sum over spin strutures required by perturbative unitarity in order to extend the analysis to include type II strings

Chern-Simons Quantization of (2+1)-Anti-De Sitter Gravity on a Torus [PDF]
, 1994 Chern-Simons formulation of 2+1 dimensional Einstein gravity with a negative cosmological constant is investigated when the spacetime has the topology $ R\times T^{2}$. The physical phase space is shown to be a direct product of two sub-phase spaces each

Eisenstein Series and String Thresholds [PDF]
, 1998 We investigate the relevance of Eisenstein series for representing certain $G(Z)$-invariant string theory amplitudes which receive corrections from BPS states only. $G(Z)$ may stand for any of the mapping class, T-duality and U-duality groups $Sl(d,Z)$, $

Some Extensions of Fixed Point Results over Quasi-JS-Spaces
Journal of Function Spaces, 2016 We introduce the notion of quasi-JS-metric space. After defining the basic topological properties of quasi-JS-metric space, we investigate fixed point of certain mapping in the frame of complete quasi-JS-metric space.
