Advancements in fixed point theory in modular function spaces

open access: yesArabian Journal of Mathematics, 2012
The purpose of this paper is to give an outline of the recent results in fixed point theory for asymptotic pointwise contractive and nonexpansive mappings, and semigroups of such mappings, defined on some subsets of modular function spaces.

Correlation function of modular Hamiltonians

open access: yesJournal of High Energy Physics, 2019
We investigate varies correlation functions of modular Hamiltonians defined with respect to spatial regions in quantum field theory. These correlation functions are divergent in general.

MOCK THETA FUNCTIONS AND QUANTUM MODULAR FORMS

open access: yesForum of Mathematics, Pi, 2013
Ramanujan’s last letter to Hardy concerns the asymptotic properties of modular forms and his ‘mock theta functions’. For the mock theta function $f(q)$, Ramanujan claims that as $q$ approaches an even-order $2k$ root of unity, we have $$\begin{eqnarray ...

Asymptotic expansions, $L$-values and a new Quantum Modular Form [PDF]

open access: yes, 2013
In 2010 Zagier introduced the notion of a quantum modular form. One of his first examples was the "strange" function $F(q)$ of Kontsevich. Here we produce a new example of a quantum modular form by making use of some of Ramanujan's mock theta functions ...

Best proximity points in modular function spaces

open access: yes, 2015
We generalize the notion of best proximity points in the context of modular function spaces. We have found sufficient conditions for the existence and uniqueness of best proximity points for cyclic maps in modular function spaces.

Neutrino masses and mixing from double covering of finite modular groups

open access: yesJournal of High Energy Physics, 2019
We extend the even weight modular forms of modular invariant approach to general integral weight modular forms. We find that the modular forms of integral weights and level N can be arranged into irreducible representations of the homogeneous finite ...

On three theorems of Folsom, Ono and Rhoades

open access: yes, 2013
In his deathbed letter to Hardy, Ramanujan gave a vague definition of a mock modular function: at each root of unity its asymptotics matches the one of a modular form, though a choice of the modular function depends on the root of unity. Recently Folsom,

Fixed points of multivalued mappings in modular function spaces with a graph

open access: yes, 2015
Let ρ∈ℜ$\rho\in\Re$ (the class of all nonzero regular function modulars defined on a nonempty set Ω) and G be a directed graph defined on a subset C of Lρ$L_{\rho}$.

S-duality in Abelian gauge theory revisited

open access: yes, 2011
Definition of the partition function of U(1) gauge theory is extended to a class of four-manifolds containing all compact spaces and certain asymptotically locally flat (ALF) ones including the multi-Taub--NUT spaces. The partition function is calculated
