Title: From Arhangel’skii’s Theorem to Hodel’s Theorem

Abstract: The plan of the lecture  is to finish the proof of factorizability and stability of any product of Lindelof Sigma-spaces. If time permits, then we will also present the Hodel’s Theorem about spaces that are hereditarily Lindelof Sigma and explain the first steps in its proof.
