Transplantation of Local Nets and Geometric Modular Action on Robertson-Walker Space-Times [PDF]

open access: yes, 2000
A novel method of transplanting algebras of observables from de Sitter space to a large class of Robertson-Walker space-times is exhibited. It allows one to establish the existence of an abundance of local nets on these spaces which comply with a ...

Nadler’s Theorem on Incomplete Modular Space

open access: yesMathematics, 2021
This manuscript is focused on the role of convexity of the modular, and some fixed point results for contractive correspondence and single-valued mappings are presented.

On a property of ϕ-variational modular spaces [PDF]

open access: yesOpuscula Mathematica, 2010
Maligranda pointed out whether condition (B.1) is satisfied in the variational modular space \(X_{\rho}^{*}\) is an open problem. We will answer this open problem in \(X_{\rho}^{*\prime}\), a subspace of \(X_{\rho}^{*}\).

On w-Isbell-convexity

open access: yesApplied General Topology, 2022
Chistyakov introduced and developed a concept of modular metric for an arbitrary set in order to generalise the classical notion of modular on a linear space.

Cyclic $(\alpha ,\beta )$-Admissible Mappings in Modular Spaces and Applications to Integral Equations

open access: yesUniversal Journal of Mathematics and Applications, 2019
The main concern of this study is to present a generalization of Banach's fixed point theorem in some classes of modular spaces, where the modular is convex and satisfying the $\Delta _{2}$-condition.

Fixed point theorems in a new type of modular metric spaces

open access: yesFixed Point Theory and Applications, 2018
In this paper, considering both a modular metric space and a generalized metric space in the sense of Jleli and Samet (Fixed Point Theory Appl. 2015:61, 2015), we introduce a new concept of generalized modular metric space.

Gauss-Manin connections for p-adic families of nearly overconvergent modular forms [PDF]

open access: yes, 2014
We interpolate the Gauss-Manin connection in p-adic families of nearly overconvergent modular forms. This gives a family of Maass-Shimura type differential operators from the space of nearly overconvergent modular forms of type r to the space of nearly ...

Some Fixed Point Results of Kannan Maps on the Nakano Sequence Space

open access: yesJournal of Function Spaces, 2021
In the recent past, some researchers studied some fixed point results on the modular variable exponent sequence space ℓr.ψ, where ψv=∑a=0∞1/ravara and ra≥1. They depended on their proof that the modular ψ has the Fatou property.

Integrating simple genus two string invariants over moduli space

open access: yesJournal of High Energy Physics, 2021
We consider an Sp(4, ℤ) invariant expression involving two factors of the Kawazumi-Zhang (KZ) invariant each of which is a modular graph with one link, and four derivatives on the moduli space of genus two Riemann surfaces.
