Title: Cancellation Theorems in Group Theory
Speaker: A. R. Shastry, IIT Bombay
Abstract: Let CG be a class of groups. A group A in CG is called cancellative if whenever G and H are in CG and G x A and H x A are isomorphic then so are G and H. We shall discuss a number of classes of groups and some cancellative groups therein.
