Abstract:
Two groups \(L_1\) and \(L_2\) are called compatible if there is a group \(G\) with two isomorphic normal subgroups \(N_1\) and \(N_2\) such that \(G/N_1\cong L_1\) and \(G/N_2\cong L_2\).
In this talk, we will introduce two concepts, namely inverse limits (which is from category theory) and generalized wreath products, and see how these concepts apply on the compatibility.
