| Resumo | |
Let D be a division ring with center Z of char not equal 2, with an involution*. Let D dagger be the multiplicative group of D, and let N D dagger be a normal subgroup. An element u is an element of D dagger is said to be symmetric (unitary) if u* = u (respectively u* = u-1). Let U be the group of unitary units of D, and let NU be a non-central subgroup. Under some mild conditions we show that N contains a free unitary pair. We also present some results for the presence of free symmetric pairs in N D dagger. (AU) | |
