Title: The rank of random matrices over finite fields

Speaker: Jane Gao Affiliation: University of Waterloo Room: MC 5501

Abstract:

We determine the rank of a random matrix over a finite field with prescribed numbers of non-zero entries in each row and column. As an application we obtain a formula for the rate of low-density parity check codes.
