Some Double Integrals Involving Multivariable I-Function

Abstract

A remarkably large number of integral formulas involving diverse special functions have been presented. In this sequel, we aim to establish two double definite integral formulas whose integrands include the multivariable I-function. The integral formulas presented here, being very general, are found to reduce to yield a large number of relatively simple integral formulas whose integrands contain various special functions deducible from the multivariable I-function, just two of which are demonstrated.
