I Added a definition of int(A) so that our open set defintion would work, and I removed CZ's comment. In defining int(A) our class notes speak of B's intersection with M being a subset of A, for A being a subset of M. Is this necessary? For whatever A we're dealing with wouldn't a ball be defined for it. For example if A is 2-d a ball would be a disc. So why bother with B's interection with M? Does this make any sense?-Aaron
