Title pre-talk: Syzygies of adjoint linear series on projective varieties
Abstract pre-talk: We overview the basic techniques in the study of syzygies of algebraic varieties and recall a proof of Green’s theorem as an important example of their application.
Title talk: Syzygies of adjoint linear series on projective varieties
Abstract tak: Syzygies of algebraic varieties have long been a topic of intense interest among algebraists and geometers alike. Starting with the pioneering work of Mark Green on curves, numerous attempts have been made to extend these results to higher dimensions. Ein and Lazarsfeld proved that if A is a very ample line bundle, then K_X + mA satisfies property N_p for any m>=n+1+p. It has ever since been an open question if the same holds true for A ample and basepoint free. In joint work with Purnaprajna Bangere we give a positive answer to this question.
