For a Kleinian group (of the first kind), no automorphic function/form has been studied before. In this note, their motivation is presented with a historical background.This is the version published by Geometry & Topology Monographs on 19 March 2008Geometric TopologyMetric Geometry11F55, 14P05, 57M25text
