Title: Separated and proper morphisms of schemes

Abstract: The basic theory of separated and proper morphisms of schemes, developed by Grothendieck, is explained in Hartshorne's book  `Algebraic Geometry' chapter 2 section 4. We will look at it from the perspective of functors of points. The functorial point of view is essential for Artin's extension of the theory of such morphisms first to algebraic spaces and then to algebraic stacks, which are going to be our next topics.

Title: Modules over Weyl algebras with application to local cohomology modules over polynomial rings-III

Abstract: Let $K$ be a field of characteristic zero. We study finitely generated modules over the  Weyl algebra A_n(K). We give application to local cohomology modules of K[X_1,...., X_n]
