I'm not sure what to make of the equation
,
though I believe I understand the Z_p action on the Tate module.
Shouldn't it be ? That is, we define the n-th approximation of z acting on a by taking the (z mod p^n)-th multiple of the n-th approximation of a. Is there any meaning to the extra subscripts n in the current equation?

Typically, the notation is a shortening of (where I here is the index set of positive integers), i.e. the extra n is there to indicate that we are dealing with a tuple.
