Although those interested in measure theory here are a set of measure zero, I have nonetheless written an article on the subject. Along with a bit of inappropriate humor, I have careened off of continuity, equivalence classes, orderings, lattices and semilattices, order topologies, and metrics. Oh, and the subject is change of variable.

Point-set topology is the branch of mathematics that deals with collections of points endowed with sufficient structure to make meaningful the notions of closeness, separation, and convergence. Beginning with familiar notions concerning open sets, closed sets, and convergence on the real number line and Euclidean plane, this course systematically develops the theory of arbitrary topological spaces. Topics include bases and subbases, separation axioms (Hausdorff, regular, and normal spaces), countability (first- and second-countable spaces), compactness and compactification, connectedness, and convergence (nets and filters). Instruction emphasizes examples and problem solving. The course appeals to those seeking a better understanding of the algebraic and geometric underpinnings of common mathematical constructs.

As usual, there’s no recommended textbook (yet), and he generally provides his own excellent notes over a required textbook. I’d suspect that he’ll recommend an inexpensive Dover Publication text like those of Kahn, Baum, or Gamelin & Greene.

If you’re curious about what’s out there, I’ve already compiled a bibliography of the usual suspects in the space:
