Analysis

[ladylove]

Anybody could help me on this:

a.) Determine the sigma-algebra generated by the nowhere dense subsets of a topological space.

b.) Let {An} be an element of A. If each An is a meager, then the union of An is also an element of A

Please post new questions in new topics, not in replies to existing topics. And look for homework help in the homework help forum.

Anyways, what have you done thus far?
