... zeta functions [1]. Here we provide a new generalization of the Riemann zeta function that is also related to the eFD and eBE functions and to the Hurwitz-Lerch zeta function. We study its properties ... The relation between the function and the general Hurwitz zeta function is exploited to deduce new identities. Keywords: Riemann zeta function, Hurwitz zeta function, Polylog...
