PROPERTY (FA) OF THE GAUSS–PICARD MODULAR GROUP
Published online by Cambridge University Press: 15 March 2011
Abstract
In this note, we prove that the Gauss–Picard modular group PU(2,1;Θ1) has Property (FA). Our result gives a positive answer to a question by Stover [‘Property (FA) and lattices in SU(2,1)’, Internat. J. Algebra Comput.17 (2007), 1335–1347] for the group PU(2,1;Θ1).
