Abstract

Number theory has been a subject of pure mathematics for a long period of time. A significant change in recent decades is that it has become an applied subject, driven by various applications to modern information technology. This talk will highlight some new applications of number theory, especially lattices and algebraic number theory, to the design of capacity-achieving codes for wireless communications and to the construction of cryptosystems with resilience against quantum attacks (aka post-quantum cryptography). One particular problem is concerned with beta-expansion for the design of polar codes in the upcoming 5G mobile networks.
