## Nigel Boston – University of Wisconsin – Madison

Low-Rank Matrix Completion I shall describe recommender systems such as Netflix, which seek to complete arrays from sparse data, and explain our recent work using algebraic geometry to obtain uniqueness results.

Linearized polynomial modules and their application to network coding Linearized polynomials are a certain family of polynomials over finite fields. They form a non-commutative ring with the two operations addition and composition. In this ring we will consider special modules…

The LWE-based key exchange Public key cryptosystems (PKC) are a critical part of the foundation of modern communication systems, in particular, the Internet. However Shor’s algorithm shows that the existing PKC like Diffie-Hellmann key exchange, RSA and ECC can be broken by…

Combinatorics of MacWilliams identities In coding theory, a MacWilliams identity expresses a linear relation between the weight distribution of a code and the weight distribution of the dual code. The transformation is characterized by its "Krawtchouk coefficients". When studying additive codes in finite abelian groups,…
