Let G(n)=Sp(n,1) or SU(n,1) . We classify conjugation orbits of generic pairs of loxodromic elements in G(n) . Such pairs, called ‘nonsingular’, were introduced by Gongopadhyay and Parsad for SU(3,1) . We extend this ...

In this paper we consider a group generated by two unipotent parabolic elements of SU(2,1) with distinct fixed points. We give several conditions that guarantee the group is discrete and free. We also give a result on the ...
