Products of Incomplete gamma functions Integral representations

In this paper we find integral representations, involving incomplete gamma and incomplete beta functions, of products of incomplete gamma functions. Also, in this paper we find interesting relations between incomplete gamma functions and Laplace transform. Since the error function is an incomplete gamma function, we find interesting relations between error functions and Laplace transform. Using the results above we find several interesting integrals.

Keywords:

: Incomplete gamma functions, Incomplete beta functions, error functions Laplace transform,
