摘要

The fundamental aim of this article is to investigate an extension of the generalized Beta function introduced in (Chaudhry et al. in J. Comput. Appl. Math. 78(1):19–32, 1997) from two variables to three or more variables. The properties of such extended functions are studied in a systematic manner and some inequalities are also discussed. An application for the so-called Laguerre polynomials in n-variables is presented as well.
