Abstract

Exton [Hypergeometric functions of three variables, J. Indian Acad. Math. 4 (1982), 113~119] introduced 20 distinct triple hypergeometric functions whose names are <TEX>$X_i$</TEX> (i = 1, ..., 20) to investigate their twenty Laplace integral representations whose kernels include the confluent hypergeometric functions <TEX>$_oF_1$</TEX>, <TEX>$_1F_1$</TEX>, a Humbert function <TEX>${\Psi}_2$</TEX>, a Humbert function <TEX>${\Phi}_2$</TEX>. The object of this paper is to present 16 (presumably new) integral representations of Euler type for the Exton hypergeometric function <TEX>$X_2$</TEX> among his twenty <TEX>$X_i$</TEX> (i = 1, ..., 20), whose kernels include the Exton function <TEX>$X_2$</TEX> itself, the Appell function <TEX>$F_4$</TEX>, and the Lauricella function <TEX>$F_C$</TEX>.
