Abstract

A local limit theorem for random walks in the hyperbolic Poincaré space of dimension \(n\ge 2\) is proved. To this end, we use the model of a ball and describe the walk in it by means of the Möbius addition and multiplication. This also enables us to derive the corresponding law of large numbers.
