Here in this paper we aim at establishing some new unified integral and differential formulas associated with the H-function. Each of these formula involves a product of the H-function and Srivastava polynomials with essentially arbitrary coefficients and the results are obtained in terms of two variables H-function. By assigning suitably special values to these coefficients the main results can be reduced to the corresponding integral formulas involving the classical orthogonal polynomials including for example Hermite Jacobi Legendre and Laguerre polynomials. Furthermore the H-function occurring in each of main results can be reduced under various special cases. 1. Introduction and preliminaries The Fox s H-function is defined and represented in the following manner [13: [ 1.1 Hpq mn z ajαj 1p b j 1 θs z s ds 1q 2πi L where i 1 and 1.2 θs m j1 Γb j s n j1 Γ1a j +α j s q jm+1 Γ1b j + s p jn+1 Γa j α j s. The nature of the contour L of the integral 1.1 the conditions of existence of the H-function defined by 1.1 and other details can be found in the book Kilbas and Saigo [8. A lot of research work has been recently come up on the study and development of a function that is more general than Fox s H-function known as H-function. The H-function was introduced by Inayat-Hussain [6 7 which is Received December ; Revised March Mathematics Suect Classification. 26A33 33C45 33C60 33C70.

It may be noted that the θξ contains fractional powers of some of the gamma function and MNPQ are integers such that 1 M Q 1 N P. Also a j 1P and b j 1Q are complex parameters; α j 1P 1Q are positive real numbers not all zero simultaneously and the exponents A j 1N and B j M+1Q may take non-integer values which we assume to be positive for standardization purpose. The nature of contour L sufficient conditions of convergence of defining integral 1.4 and other details about the H-function reader can also refer the papers [ for more detail. The behavior of the H-function for small values of z and sufficient conditions for the absolute convergence of the defining integral follows easily [ H MN PQ [z o z α where 1.6 α min 1 j M Re M N 1.7 Ω + A j α j j1 j1 Q jm+1 z 0 B j P jn+1 α j > 0 and arg z < 1 2 Ωπ.

The results have been given in terms of the product of one variable H-function and Srivastava polynomials in a compact and elegant form the results are obtained in terms of two variables H-function. A specimen of some of interesting special cases of main integral formula is presented briefly. Acknowledgment.
