Evaluation of series with Hurwitz and Lerch zeta function coefficients by using Hankel contour integrals [PDF]

open access: yesApplied Mathematics and Computation, 2007
We introduce a new technique for evaluation of series with zeta coefficients and also for evaluation of certain integrals involving the logGamma function. This technique is based on Hankel integral representations of the Hurwitz zeta, the Lerch Zeta, the Digamma and logGamma functions.

Differential subordinations and superordinations for meromorphic multivalent functions involving a convolution operator

open access: yesAIMS Mathematics
The results of this paper deal with a few applications of the general theory of the differential subordinations and superordinations, and to obtain our results we use the general techniques of the differential subordination and superordination theory ...

Sum of the Hurwitz-Lerch Zeta Function over Prime Numbers: Derivation and Evaluation

open access: yes, 2022
For the function $f(m,p,q,n)$, where $k,s,a$ general complex numbers and $q$ any positive integer, we establish the sum of values of the Hurwitz-Lerch zeta function $\Phi(f(m,p,q,n),k,a)$ taken at prime numbers $n$. Special cases of this sum are evaluated in terms of products of trigonometric functions and Catalan's constant $K$.

The density function for the value-distribution of Lerch zeta-functions and its applications

open access: yes, 2018
The probabilistic study of the value-distribution of zeta-functions is one of the modern topics in analytic number theory. In this paper, we study a probability density function related to the value-distribution of Lerch zeta-functions.

Value distribution of Lerch and periodic Hurwitz Zeta-functions

open access: yes, 2018
In this dissertation the Lerch zeta-function, its derivative and the periodic Hurwitz zeta-function are studied. These functions are generalizations of the famous Riemann zeta-function. To get better understanding of the zero and a-value distribution of the periodic Hurwitz zeta-function we find the asymptotic formula for the number of nontrivial zeros
