Hi, let ##h: A \rightarrow A ##be a homomorphism between algebraic structures. Is there a nice result describing the
properties of ##Ker h^2 ## , where ##h^2 = hoh ## (composition) ? Clearly , ## ker( h) \subset ker (h^2 )## , but are there some other results relating the two; maybe relating kerh to ker h^n?
