Complex hyperbolic 2-orbifolds with isolated singularities

Abstract

For each prime pp, this paper constructs compact complex hyperbolic 22-manifolds with an isometric action of Z/pZ\mathbb{Z} / p \mathbb{Z} that is not free and has only isolated fixed points. The case p=2p = 2 is special, and finding general examples for p=2p=2 is related to whether or not complex hyperbolic lattices are conjugacy separable on torsion.
