Title: Separated and Proper Morphisms
Abstract: Separated morphisms, and proper morphisms, are two very important classes of morphisms in algebraic geometry. In the next few lectures, we will study these for schemes, algebraic spaces, and algebraic stacks. The basic theory of such morphisms between schemes is given in Hartshorne's `Algebraic Geometry', Chapter 2, Section 4. After recalling the basics, we will go on to consider such morphisms between algebraic spaces and then between algebraic stacks. The first lecture should be easily accessible to beginner students in algebraic geometry.

Title: Generalized Cesaro summability in higher order Dirichlet type spaces
Abstract: Corresponding to every positive Borel measure on the unit circle and an integer, we shall consider weighted Dirichlet-type spaces. We will see that every member of these spaces can be approximated by certain generalized Cesaro mean.
