Title: A combinatorial approach to Grassmann codes - I
Speaker: Fernando Pinero, IIT Bombay
Abstract: In this series of talks we will consider Grassmann codes from the perspective of the partial geometry given by the points and lines of the Grassmannian. First we start with the case of the "affine part" of the Grassmannian and its associated code, the Affine Grassmann codes. Based on results from Beelen, Ghorpade and Hoholdt, we extend this to Grassmann codes. With a technique based on forcing sets and irreducible k-threshold process, we also prove that analogous results for Schubert union codes.
