WebOct 7, 2011 · 973. It's the size of the "open sets", in the same sense that a grind of flour is "finer" than another if it has been ground to a smaller size. Topology A is "finer" than topology B if and only if its contains all the sets in B and contains some additional ones that are subsets of sets in B. And, of course, in that case, B is "coarser" than A. WebMunkres, Section 26 Compact Spaces. A compact space is a space such that every open covering of contains a finite covering of ..
