Abstract
We investigate the properties of the Genocchi functions and the Genocchi polynomials. We obtain the Fourier transform on the Genocchi function. We have the generating function of -Genocchi polynomials. We define the Cangul-Ozden-Simsek's type twisted -Genocchi polynomials and numbers. We also have the generalized twisted -Genocchi numbers attached to the Dirichlet's character . Finally, we define zeta functions related to -Genocchi polynomials and have the generating function of the generalized -Genocchi numbers attached to .
1. Introduction
After Carlitz introduced an interesting -analogue of Frobenius-Euler numbers in [1], -Bernoulli and -Euler numbers and polynomials have been studied by several authors. Recently, many authors have an interest in the -extension of the Genocchi numbers and polynomials(cf. [2–5]). Kim et al. [5] defined the -Genocchi numbers and the -Genocchi polynomials. In [3], Kim derived the -analogs of the Genocchi numbers and polynomials by constructing -Euler numbers. He also gave some interesting relations between -Euler and -Genocchi numbers. The first author et al. [6] obtained the distribution relation for the Genocchi polynomials.
The main aim of this paper is to derive the Fourier transform for the Genocchi function. Recently, Kim [7] investigated the properties of the Euler functions and derived the interesting formula related to the infinite series by using the Fourier transform for the Euler function. In this paper, we investigate some arithmetical properties of the Genocchi functions and the Genocchi polynomials.
In [8], Cangul-Ozden-Simsek constructed new generating functions of the twisted -extension of twisted Euler polynomials and numbers attached to the Dirichlet character . Cangul et al. [8] also defined the twisted -extension of zeta functions, which interpolate the twisted -extension of Euler numbers at negative integers. In this paper, we define the Cangul-Ozden-Simsek type twisted -Genocchi polynomials and numbers. We have the generating function of -Genocchi polynomials. We have the generalized twisted -Genocchi numbers attached to the Dirichlet character . We define zeta functions related to -Genocchi polynomials and we have the generating function of the generalized -Genocchi numbers attached to .
