Common fixed point theorems for several multivalued mappings on proximinal sets in regular modular space

Journal of Inequalities and Applications, 2021
In this paper, we found a common fixed point for several multivalued mappings on proximinal sets in regular modular metric space. Also, we introduced the notions of conjoint F-proximinal contraction as well as conjoint F-proximinal contraction of Hardy ...

Modular Invariant Regularization of String Determinants and the Serre GAGA Principle

, 2013
Since any string theory involves a path integration on the world-sheet metric, their partition functions are volume forms on the moduli space of genus g Riemann surfaces M_g, or on its super analog.

D3-instantons, Mock Theta Series and Twistors [PDF]

, 2012
The D-instanton corrected hypermultiplet moduli space of type II string theory compactified on a Calabi-Yau threefold is known in the type IIA picture to be determined in terms of the generalized Donaldson-Thomas invariants, through a twistorial ...

Fixed point theorems of new generalized C-conditions for ( psi; gamma)-mappings in modular metric spaces and its applications

Nonlinear Analysis, 2023
This paper introduces new generalizations of the C-condition for (ψ; γ)-mappings in modular metric spaces. We extend the fixed point results for such mappings yielding the generalized C-condition in metric spaces to modular ones.We proved the existence ...

Generalized Fuzzy Torus and its Modular Properties [PDF]

, 2013
We consider a generalization of the basic fuzzy torus to a fuzzy torus with non-trivial modular parameter, based on a finite matrix algebra. We discuss the modular properties of this fuzzy torus, and compute the matrix Laplacian for a scalar field.

Fixed‐Point Theorems for Multivalued Mappings in Modular Metric Spaces [PDF]

Abstract and Applied Analysis, 2012
We give some initial properties of a subset of modular metric spaces and introduce some fixed‐point theorems for multivalued mappings under the setting of contraction type. An appropriate example is as well provided. The stability of fixed points in our main theorems is also studied.

Unitary Equivalence of the Metric and Holonomy Formulations of 2+1 Dimensional Quantum Gravity on the Torus

, 1992
Recent work on canonical transformations in quantum mechanics is applied to transform between the Moncrief metric formulation and the Witten-Carlip holonomy formulation of 2+1-dimensional quantum gravity on the torus.

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 $Sl(d,Z)$, $
