A QUADRUPLE INTEGRAL INVOLVING THE EXPONENTIAL LOGARITHM OF QUOTIENT RADICALS IN TERMS OF THE HURWITZ-LERCH ZETA FUNCTION

open access: yesUral Mathematical Journal, 2022
With a possible connection to integrals used in General Relativity, we used our contour integral method  to write a closed form solution for a quadruple integral involving exponential functions and  logarithm of quotient radicals.

The Mellin Transform of Logarithmic and Rational Quotient Function in terms of the Lerch Function

open access: yesJournal of Mathematics, Volume 2021, Issue 1, 2021., 2021
Upon reading the famous book on integral transforms volume II by Erdeyli et al., we encounter a formula which we use to derive a Mellin transform given by ∫0∞xm−1logkax/β2+x2γ+xdx, where the parameters a, k, β, and γ are general complex numbers. This Mellin transform will be derived in terms of the Lerch function and is not listed in current literature

Solution of fractional kinetic equations involving generalized Hurwitz-Lerch Zeta function using Sumudu transform

open access: yes, 2021
Fractional kinetic equations (FKEs) comprising a large array of special functions have been extensively and successfully applied in specification and solving many significant problems of astrophysics and physics.

Leaf-to-leaf distances and their moments in finite and infinite m-ary tree graphs [PDF]

open access: yes, 2015
We study the leaf-to-leaf distances on full and complete m-ary graphs using a recursive approach. In our formulation, leaves are ordered along a line. We find explicit analytical formulae for the sum of all paths for arbitrary leaf-to-leaf distance r as

Twisted Eisenstein series, cotangent‐zeta sums, and quantum modular forms

open access: yesTransactions of the London Mathematical Society, Volume 7, Issue 1, Page 33-48, December 2020., 2020
Abstract We define twisted Eisenstein series Es±(h,k;τ) for s∈C, and show how their associated period functions, initially defined on the upper half complex plane H, have analytic continuation to all of C′:=C∖R⩽0. We also use this result, as well as properties of various zeta functions, to show that certain cotangent‐zeta sums behave like quantum ...

Asymptotic expansions of the Hurwitz–Lerch zeta function

open access: yesJournal of Mathematical Analysis and Applications, 2004
In the paper, a generalization of the asymptotic expansions obtained by \textit{M.~Katsurada} [Proc.~Japan Acad. 74, No. 10, 167--170 (1998; Zbl 0937.11035)] and \textit{D.~Klusch} [J.~Math. Anal. Appl. 170, No. 2, 513--523 (1992; Zbl 0763.11036)] for the Lipschitz-Lerch zeta function \[ R(a, x, s)\equiv\sum_{k=0}^\infty {e^{2k\pi ix}\over (a+k)^s ...

Around the Lipschitz Summation Formula

open access: yesMathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
Boundary behavior of important functions has been an object of intensive research since the time of Riemann. Kurokawa, Kurokawa‐Koyama, and Chapman studied the boundary behavior of generalized Eisenstein series which falls into this category. The underlying principle is the use of the Lipschitz summation formula.

A Generalization of the Secant Zeta Function as a Lambert Series

open access: yesMathematical Problems in Engineering, Volume 2020, Issue 1, 2020., 2020
Recently, Lalín, Rodrigue, and Rogers have studied the secant zeta function and its convergence. They found many interesting values of the secant zeta function at some particular quadratic irrational numbers. They also gave modular transformation properties of the secant zeta function.

A New Family of the λ-Generalized Hurwitz-Lerch Zeta Functions with Applications [PDF]

open access: yes, 2014
: Motivated largely by a number of recent investigations, we introduce and investigate the various properties of a certain new family of the λ-generalized Hurwitz-Lerch zeta functions.
