Identification of the dual of Lp spaces and the dual of Cc(X) with detail exposition and proofs.  Proofs for both real and complex versions when X is locally compact as well as the dual for BC(X) the space of bounded continuous real valued functions when X is normal and Hausdorff are presented.  A brief discussion when X is completely regular and Hausdorff is added.

cal4.gif (2638 bytes) Convergence In Measure  New

Convergence in measure or in probability, a notion often used in probability theory. Convergence almost uniformly and convergence almost everywhere, Egoroff's theorem. As is expected, for a probability space, convergence almost everywhere implies convergence in measure.  Monotone Convergence theorem, Bounded Convergence THeorem and Dominated Convergence Theorem for Convergence in measure. Fatou's Lemma.
