Commutative algebra seminar Title: Depth of higher associated graded modules Abstract: Let (A,m) be a Noetherian local ring with depth(A) > 1, I an m-primary ideal, M a finitely generated A-module of dimension r, and G_n, the associated graded module of M with respect to I^n. We will discuss a necessary and sufficient condition for depth (G_n) > 1 for all sufficiently large. This talk is based on a paper by Tony Joseph Puthenpurakal (Ratliff-Rush filtration, regularity and depth of higher associated graded modules: Part I )

Description:
Title: Parabolic bundles in positive characteristic. Abstract: In this talk algebraic parabolic bundles on smooth projective curves over algebraically closed field of positive characteristic is defined. We will show that the category of algebraic parabolic bundles is equivalent to the category of orbifold bundles defined in. Tensor, dual, pullback and pushforward operations are also defined for parabolic bundles.
