1. Introduction and preliminaries.

Recently the authors, see ([8],[11]-[14]) have been investigated the applications of the Riemann-Liouville and Kober fractional q-integral operators to various basic hypergeometric function of one variable including the basic analogue of Fox’s H-function. These results are a new contribution to the theory of q-fractional calculus. Motivated by these works, and a possible scope for their application in evaluation and solution of the q-integral equations, we further explore the possibility of evaluation of Kober type fractional q-integrals involving basic analogue of multivariable H-function and.basic analogue of multivariable Meijer-function and.

Also, the basic analogue of the Kober fractional integral operator, see Agarwal [1] is defined by

Following Agarwal [1], Al-Salam [2] and Jackson [4] the basic integration is defined as

If the basic analogue of multivariable H-function reduces to basic of Srivastava-Daoust function, see the work of Yadav et al. [13].

We obtain the same relations with basic analogue of H-function of two variables and one variable and basic analogue of Meijer-function of two variables and one variable. The basic analogue of H-function of two variables and the basic analogue of H-function of one variables are defined by Saxena et al. [7] and [6] respectively.

5. Conclusion.

The importance of our all the results lies in their manifold generality. By specialising the various parameters as well as variables in the basic analogue of multivariable H-function and the basic analogue of multivariable Meijer-function, we obtain a large number of results involving remarkably wide variety of useful basic functions ( or product of such basic functions) which are expressible in terms of basic H-function, Basic Meijer’s G-function, Basic E-function, basic hypergeometric function of one and two variables and simpler special basic functions of one and two variables. Hence the formulae derived in this paper are most general in character and may prove to be useful in several interesting cases appearing in literature of Pure and Applied Mathematics and Mathematical Physics.
