The possible configurations of fixed points for quasi-perspectivities are determined (extending results of R. Baer), and restrictions to the structure of finite quasiperspective groups as well as bounds for the dimension of quasi-perspective groups are derived.eninfo:eu-repo/semantics/openAccessStabile Ebene , Topologische Geometrie510article
