Integral type contractions in modular metric spaces [PDF]
Journal of Inequalities and Applications, 2013 Abstract We prove the existence and uniqueness of a common fixed point of compatible mappings of integral type in modular metric spaces. MSC:47H09, 47H10, 46A80.

Journal of Mathematics, 2021 Extending the Presic type operators to modular spaces, we introduce generalised Presic type w-contractive mappings and strongly w-contractive mappings in a modular metric space and establish fixed-point theorems for such contractions in modular spaces ...

Mathematics, 2016 The purpose of this paper is to present a new approach to study the existence of fixed points for multivalued F-contraction in the setting of modular metric spaces. In establishing this connection, we introduce the notion of multivalued F-contraction and

Hybrid pair of multivalued mappings in modular-like metric spaces and applications
AIMS Mathematics, 2022 Our aim is to prove some new fixed point theorems for a hybrid pair of multivalued α∗-dominated mappings involving a generalized Q-contraction in a complete modular-like metric space.

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.

Mathematics, 2023 In the realm of generalized modular metric spaces, we substantiate the validity of fixed-point theorems with Branciari contractions. This paper expands and broadens the original theorems in this context. Subsequently, by building upon this foundation, we

QUANTUM ASPECTS OF 2+1 GRAVITY [PDF]
, 1995 We review and systematize recent attempts to canonically quantize general relativity in 2+1 dimensions, defined on space-times $\R\times\Sigma^g$, where $\Sigma^g$ is a compact Riemann surface of genus $g$.

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.
