On integral representations and asymptotics of some hypergeometric functions in two variables
Abstract
The leading asymptotic behaviour of the Humbert functions $Φ_2$, $Φ_3$, $Ξ_2$ of two variables is found, when the absolute values of the two independent variables become simultaneosly large. New integral representations of these functions are given. These are re-expressed as inverse Laplace transformations and the asymptotics is then found from a Tauberian theorem. Some integrals of the Humbert functions are also analysed.
