Title: Applications of Alexander Duality

Abstract: In this talk we will explore two important applications of Alexander duality. In the previous talk, we discussed the Alexander dual of a square-free monomial ideal. In this talk we will drop the square-free assumption and define Alexander duality in that setting. This will have an important application regarding a certain kind of decomposition of monomial ideals. The second application we will study has to do with resolutions of Alexander ideals. In studying this application, we will briefly review some homological algebra concepts such as the Zigzag Lemma.
