On FoxH Function Fractional Integral Operators And M Series
RAHUL SOLANKI A.M. KHAN
In the present investigation, the fractional operators involving FoxH function due to Saxsena Kumbhat, are applied to the M series which is further extension of both MittagLeffler function and generalized hypergeometric function pFq. The Hfunction fractional operators have found essential application in the solution of kinetic equation, fractional reaction and fractional diffusion. The results are mostly derived in a closed form in the terms of the Hfunction suitable for numerical computation.

1. Introduction and Preliminaries:
The Subject of fractional calculus deals with investigations of integrals and derivatives has gained importance and popularity during the last four decades or so, mainly due to its vast potential demonstrated applications in fields of science and engineering . Different extensions of various fractional integrations operators are studied by Kalla [14] , Mc Bride [5], Kilbas
[1] ,Kiryakova [4A] , Purohit Kalla [13] etc.In the present paper we introduce a fractional integral operator involving H function for Re(a) > 0, ai, bj , aj, {3j > 0, i = 1 p; j = 1 . q , pE , > 0 as follows

The Properties of these operators were studied by Saigo [ ] Mathai & Saxena [ ] following which we can easily obtain sided and right handed sided generalized integration of type
( 1.1 ) and ( 1.2 ) for power function as follows :

Sharma and Jain [7A] introduced the generalized Mseries as the function defined by means of the power series:
aM/3(a , a , , a
; b , b , b ; z) = aM/3(z) = aM/3 ((a )p ; (b )q; z)
p q 1 2 p 1 2 q p q

n

, z, a, {3 C, R(a) > 0 (1.9)
n=O
(b1)n (bq)n
(an + {3)
where,(aj)n, (bj)n are the known Pochammer symbols. The series (1.7) is defined when none of the parameters bj s, j = 1, 2, , q, is a negative integer or zero; if any numerator parameter aj is a negative integer or zero, then the series terminates to a polynomial in z. The series in
(1.7) is convergent for all z if p q, it is convergent for z < o if p = q + 1 and divergent, if p > q + 1. When p = q + 1 and z = , the series can converge on conditions depending on the parameters. Properties of Mseries are further studied by Saxena [8A], Chouhan and Sarswat [9A] etc.
The generalized Mittag Leffler function [10A], is obtained from (1.7) for p = q = 1;
a = y C; b = 1, as

The generalized Mseries (1.7) can be represented as a special case of the Wright generalized hypergeometric function (1.6), as
aM/3 ((a )p ; (b )q ; z) = k 1/
(a1, 1), , (ap, 1), (1,1);

1. Main Results:
In this section, the image formulas for the Mseries involving FoxH Function fractional integral operators (1.1) and (1.2) are established:
Theorem 2.1 Let m, n, p, q NO with 0 n p, 1 m q, aj ,{3j R+ ,aj , bj R or C , i = 1, p , j = 1, q, Re(a) > 0, a C.
a = 0, yÂµ + R(o) < 1; amin R (bj) + R(p) > 0 and ya < R(p).
