Power Set Functions
February 6, 2003
Bailey Hall 100
Recall that the power set p (X ) is the set of all subsets of a set X . In this seminar, we will consider functions between power sets. Two examples, encountered in Math 99, are the direct image p (X ) ->p (Y ) and the inverse image p (Y ) ->p (X ) of a function f: 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.
