Strong Discreteness of Subgroups of SL(2,Гn)

摘要

@@ As in [1,6], let Гn be the n-dimensional Clifford group, i.e., the set of all elements in n-dimensional Clifford algebra An, which can be expressed as a finite product of non-zero-vectors and SL(2, Гn)denote the group of n-dimensional Clifford matrices A= (a c b d) which satisfy:
