Abstract: In the present paper we consider product of some special function associated with the pathway functional integral operator. This operator generalizes of the classical Riemann Liouville fractional integral operator. The results derived here are quite general in nature and their several known and new special cases are also obtained here.
Keywords: Pathway fractional integral operator, Fox's H function, Generalized MittagLeffler function, Gfunction.
INTRODUCTION
The Pathway fractional integral operator introduced by Nair
[9] is defined in the following mannerfor < 1it is a finite range density with [1 (1
)]1 and (1.2) remains in the extended generalized type1 beta family.
() = 1[1 + ( 1)]1 … (1.6)
Provided that < < , > 0, 0, > 1which is the extended generalized type2 beta model for real x. It includes thetype2 beta density, the Fdensity, the Cauchy density and many more.
Here we consider only the case of pathway parameter < 1. For 1,(1.2) and (1.6)take the exponential from, since

The pathway model introduced byMathai [6] and further studied bythe Mathai and Haubold[7], [8]. For real scalar, the pathway model for scalar random variables is represented by the following probability density function (p. d. f.).
() = 1[1 (1 )]1… (1.2)
= 1 … (1.7)
This include the generalized Gamma, the Weibull, the Chi square, the Laplace, Maxwell
Boltzmann and other related densities.

Special Cases:
1. If we take k=1, in theorem1 then we get the known result of
[3, eq. (2.2)].2. If we take , 0, and k=1 in theorem1 then we get the known result of [9, eq. (25) p.244].
3. If we take 0, 0, = = 1 in theorem1 then we get the known result of [9, eq. (26) p.245].
4. If we take 0, 0, = 1 e and in theorem 2 then we get the known result of [10, eq. (3.3)].
CONCLUSION
The pathway fractional integral operator is expected to have wide application in statistical distribution theory. It could help to extend some classical statistical distribution to wider classes of distribution. During the last three decades fraction calculus has been applied to almost every field of science, engineering and mathematics.
