Haifa University - Dept. of CS Theory Seminar Speaker : Adi Shraibman, Weizmann. Title: "Lower bounds on randomized and quantum communication complexity based on factorization norms" Date: Thursday, Dec. 6. Place: Haifa U. Education Building, room 570. Time: 12:15 - 13:30 Abstract: We will describe a general framework for proving lower bounds on randomized and quantum communication complexity that generalizes most of the known lower bounds. In particular we show that almost all of the known lower bounds can be explained using duality theory. Joint work with Nati Linial.
