On a new extension of extended (p,q) Beta function

The main objective of this paper is to introduce a further extension of extended (p, q)-Beta function by considering product of two Mittag-Leffler functions in the kernel. We investigate various properties of this newly defined Beta function such as integral representations, summation formulas and Mellin transform. Further, some known and new relations for various forms of extended Beta functions are obtained as special cases of the main results.
