We give a new construction of the q-extensions of Euler numbers and polynomials. We present new generating functions which are related to the q-Euler numbers and polynomials. We also consider the generalized q-Euler polynomials attached to Dirichlet s character X and have the generating functions of them. We obtain distribution relations for the q-Euler polynomials and have some identities involving q-Euler numbers and polynomials. Finally we derive the q-extensions of zeta functions from the Mellin transformation of these generating functions which interpolate the q-Euler polynomials at negative integers. 1. Introduction Let C be the complex number field. We assume that q e C with q 1 and that the q-number is defined by x q 1 - qx 1 - q in this paper. Recently many mathematicians have studied for q-Euler and q-Bernoulli polynomials and numbers see 1-18 . Specially there are papers for the q-extensions of Euler polynomials and numbers approaching with two kinds of viewpoint among remarkable papers see 7 10 . It is known that the Euler polynomials are .
