Recall that the power setp(X) is the set of all subsets of a setX. In this seminar, we will consider functions between power sets. Two examples, encountered in Math 99, are the direct imagep(X) ->p(Y) and the inverse imagep(Y) ->p(X) of a functionf: X->Y. After reviewing some properties of these "familiar" functions, we will look more closely at these properties to see if they hold for any other power set functions.
