To the cusp and back: resurgent analysis for modular graph functions

open access: yesJournal of High Energy Physics, 2022
Modular graph functions arise in the calculation of the low-energy expansion of closed-string scattering amplitudes. For toroidal world-sheets, they are SL(2, ℤ)-invariant functions of the torus complex structure that have to be integrated over the ...

Symmetry-resolved modular correlation functions in free fermionic theories

open access: yesJournal of High Energy Physics, 2023
As a new ingredient for analyzing the fine structure of entanglement, we study the symmetry resolution of the modular flow of U(1)-invariant operators in theories endowed with a global U(1) symmetry.

Extrapolation on function and modular spaces, and applications

open access: yesAdvances in Mathematics, 2022
We generalize the extrapolation theory of Rubio de Francia to the context of Banach function spaces and modular spaces. Our results are formulated in terms of some natural weighted estimates for the Hardy-Littlewood maximal function and are stated in measure spaces and for general Muckenhoupt bases. Finally, we give several applications in analysis and

Convergence Results for Total Asymptotically Nonexpansive Monotone Mappings in Modular Function Spaces

open access: yesJournal of Function Spaces, 2021
In this article, we consider an extensive class of monotone nonexpansive mappings. We use S-iteration to approximate the fixed point for monotone total asymptotically nonexpansive mappings in the settings of modular function space.

On Modified Interpolative Almost E−Type Contraction in Partial Modular b−Metric Spaces

open access: yesAxioms, 2023
The current study attempts to identify a new generalized metric space structure, referred to as partial modular b−metric, that extends both partial modular metric space via b−metric space and explains the topological aspects of the new space implementing

On the Generalised Transfer Operators of the Farey Map with Complex Temperature

open access: yesMathematics, 2022
We consider the problem of showing that 1 is an eigenvalue for a family of generalised transfer operators of the Farey map. This is an important problem in the thermodynamic formalism approach to dynamical systems, which in this particular case is ...

Fixed Points of Multivalued Maps in Modular Function Spaces [PDF]

open access: yesFixed Point Theory and Applications, 2009
AbstractThe purpose of this paper is to study the existence of fixed points for contractive-type and nonexpansive-type multivalued maps in the setting of modular function spaces. We also discuss the concept of "Equation missing"-modular function and prove fixed point results for weakly-modular contractive maps in modular function spaces.

Relations between elliptic modular graphs

open access: yesJournal of High Energy Physics, 2020
We consider certain elliptic modular graph functions that arise in the asymptotic expansion around the non-separating node of genus two string invariants that appear in the integrand of the D 8ℛ4 interaction in the low momentum expansion of the four ...
