Title: Fourteen equivalent definitions of Lindelof Sigma-spaces

Abstract: This talk is an advertisement of the class of Lindelof Sigma-spaces. We will present fourteen equivalent definitions of Lindelof Sigma-spaces and explain the main idea of the proof of their equivalence. It will also be proved that the class of Lindelof Sigma-spaces has nice categorical properties which will give the audience a sufficient background for understanding non-trivial results about this class.
