Reach and complementarity of $$\mu \rightarrow e$$ μ → e searches

open access: yesEuropean Physical Journal C: Particles and Fields, 2022
In Effective Field Theory, we describe $$\mu \leftrightarrow e$$ μ ↔ e flavour changing transitions using an operator basis motivated by experimental observables. This implies that $$\mu \rightarrow e_L \gamma $$ μ → e L γ , $$\mu \rightarrow e_L \bar{e}

Simultaneous Approximation of New Sequence of Integral Type Operators with Parameter δ_0

open access: yesEuropean Journal of Pure and Applied Mathematics, 2019
In this paper, we define a new sequence of linear positive operators of integral type to approximate functions in the space,. First, we study the basic convergence theorem in simultaneous approximation and then study Voronovskaja-type asymptotic formula.

Some Fractional Operators with the Generalized Bessel–Maitland Function

open access: yesDiscrete Dynamics in Nature and Society, 2020
In this paper, we aim to determine some results of the generalized Bessel–Maitland function in the field of fractional calculus. Here, some relations of the generalized Bessel–Maitland functions and the Mittag-Leffler functions are considered. We develop

Lipschitz integral operators represented by vector measures

open access: yesApplied General Topology, 2021
In this paper we introduce the concept of Lipschitz Pietsch-p-integral mappings, (1≤p≤∞), between a metric space and a Banach space. We represent these mappings by an integral with respect to a vector measure defined on a suitable compact Hausdorff ...
