New approach to the complete sum of products of the twisted (h, q)-Bernoulli numbers and polynomials

Yilmaz Simsek; Veli Kurt; Daeyeoul Kim

Abstract In this paper, by using q-Volkenborn integral[10], the first author[25] constructed new generating functions of the new twisted (h, q)-Bernoulli polynomials and numbers. We define higher-order twisted (h, q)-Bernoulli polynomials and numbers. Using these numbers and polynomials, we obtain new approach to the complete sums of products of twisted (h, q)-Bernoulli polynomials and numbers. p-adic q-Volkenborn integral is used to evaluate summations of the following form: where is the twisted (h, q)-Bernoulli polynomials. We also define new identities involving (h, q)-Bernoulli polnomials and numbers.

ON THE ANALOGS OF BERNOULLI AND EULER NUMBERS, RELATED IDENTITIES AND ZETA AND L-FUNCTIONS

Taekyun Kim; Seog-Hoon Rim; Yilmaz Simsek; Daeyeoul Kim

In this paper, by using q-deformed bosonic p-adic integral, we give -Bernoulli numbers and polynomials, we prove Witts type formula of -Bernoulli polynomials and Gauss multiplicative formula for -Bernoulli polynomials. By using derivative operator to the generating functions of -Bernoulli polynomials and generalized -Bernoulli numbers, we give Hurwitz type -zeta functions and Dirichlets type -L-functions; which are interpolated -Bernoulli polynomials and generalized -Bernoulli numbers, respectively. We give generating function of -Bernoulli numbers with order r. By using Mellin transforms to their function, we prove relations between multiply zeta function and -Bernoulli polynomials and ordinary Bernoulli numbers of order r and -Bernoulli numbers, respectively. We also study on -Bernoulli numbers and polynomials in the space of locally constant. Moreover, we define -partial zeta function and interpolation function.

Yilmaz Simsek; Ismail Naci Cangul; Veli Kurt; Daeyeoul Kim

The main purpose of this paper is to study on generating functions of the Open image in new window -Genocchi numbers and polynomials. We prove new relation for the generalized Open image in new window -Genocchi numbers which is related to the Open image in new window -Genocchi numbers and Open image in new window -Bernoulli numbers. By applying Mellin transformation and derivative operator to the generating functions, we define Open image in new window -Genocchi zeta and Open image in new window -functions, which are interpolated Open image in new window -Genocchi numbers and polynomials at negative integers. We also give some applications of generalized Open image in new window -Genocchi numbers.The main purpose of this paper is to study on generating functions of the -Genocchi numbers and polynomials.
