WebThis result gives rise to many geometric constraints for discrete Mobius groups. In the study of the iterative commutator sequences, one makes use of the fact that three trace parameters tr$\sp2(f),\ {\rm tr}\sp2(g),$ and tr (f,g) determine the two generator group $\langle f,g\rangle$ up to conjugacy whenever tr (f,g) is not equal to 2.

WebDec 17, 1997 · In this article, we begin a study of discrete subgroups of complex hyperbolic motions. We present necessary conditions for two generator subgroups of the holomorphic isometry group of complex hyperbolic 2-space (which may be identi®ed with PU(2,1)) to be discrete. These results are reminiscent of Jùrgensen's inequality from the theory of …
