Introduction The purpose of this paper is to derive formulae for the sums of products of the q-Euler polynomials and numbers since many identities can be obtained from our sums of products of the q-Euler polynomials and numbers. In 1 Simsek evaluated the complete sums for the Euler numbers and polynomials and obtained some identities related to Euler numbers and polynomials from his complete sums and Jang et al. 2 also considered the sums of products of Euler numbers. Kim 3 derived the sums of products of the q-Euler numbers using the fermionic p-adic q-Volkenborn integral. In this paper we will evaluate the complete sum of the q-Euler polynomials and numbers using the fermionic p-adic q-Volkenborn integral on Zp. Assume that p is a fixed odd prime. Throughout this paper the symbols Zp Qp C and Cp denote the ring of p-adic rational integers the field of p-adic rational numbers the complex number field and the completion of algebraic closure of Qp respectively. Let N be the set of natural numbers. Let Vp be the
