Some identities and recurrences relations for the q-Bernoulli and q-Euler polynomials

In this article we prove some relations between two-variable q -Bernoulli polynomials and two-variable q -Euler polynomials. By using the equality $e_qinsert ignore into journalissuearticles values(z);E_qinsert ignore into journalissuearticles values(-z);=1$,   we give an identity for the two-variable q -Genocchi polynomials. Also, we obtain an identity for the two-variable q -Bernoulli polynomials. Furthermore, we prove two theorems which are analogues of the q- extension Srivastava-Pinter additional theorem
