Asymptotic expansions of the Humbert Function $\hat{I}{¦}_1$ and their applications

Peng-Cheng Hang, Liangjian Hu, Min-Jie Luo

This paper systematically studies the asymptotics of Humbert's bivariate confluent hypergeometric function $\hat{I}{¦}_1[a,b;c;x,y]$. Specifically, we establish explicit asymptotic expans…
