Parts C and D only power set topology
# 2. Let X = {1, 2, 3}, so that the power set P(X) has 2^3 = 8 elements. A topology on X is a subset of P(X) (i.e. a collection of subsets of X) which must contain both empty set and X, which...

metric space; study guide for final
# 1. In the chapter on metric spaces, before the abstract definition of a topology was given, we defined a subset U of a metric space (X, d) to be open if for all x element of U there exists e >...
