Dear  Don,
could you post the following, please:

Let A be the Steenrod algebra when p=2 or the algebra of reduced
powers for p odd. The operation of raising to the pth power in A
induces an operation on Ext_A(Z/p,Z/p) usually denoted by P^0.

My question is what is known about the kernel of P^0 in the Ext-
algebra? Particularly, is it nontrivial?

Best,
andrey
