The integral homology of PSL(2) of imaginary quadratic integers with nontrivial class group
(2011)We show that a cellular complex defined by Flöge allows us to determine the integral homology of the Bianchi groups PSL(2)(O[m]), where O[m] is the ring of integers of an imaginary quadratic number field Q [square root ...
