Abstract
We apply the Feynman–Kac formula to compute the $\lambda$-Poisson kernels and $\lambda$-Green functions for half-spaces or balls in hyperbolic spaces. We present known results in a unified way and also provide new formulas for the $\lambda$-Poisson kernels and $\lambda$-Green functions of half-spaces in ${\mathbb H}^n$ and for balls in real and complex hyperbolic spaces.
