Title: Graded algebras with pure resolution-I

Speaker: J.K.Verma, IIT Bombay

Abstract: We will give an expository account of several examples of graded algebras with pure resolution. These arise as homogeneous co-ordinate rings of projective varieties of minimal degree, rational normal scrolls, certain determinantal varieties, Pfaffian ideals, Stanley Reisner ideals of simplicial complexes whose Alexander duals are Cohen-Macaulay.
