Speaker: Noga Alon, Tel Aviv University
Title: On graphs, arithmetic progressions and communication
Tools from Extremal Graph Theory are helpful in the study of problems in Additive Number Theory, Theoretical Computer Science, and Information Theory. I will illustrate this fact by several closely related examples focusing on a recent one in a joint paper with Moitra and Sudakov.
Speaker: Persi Diaconis
Title: "An Introduction to additive combinatorics via 'carries'"
When numbers are added in the usual way, "carries" occur. The chance of a carry is about .45 (base 10). There are other choices of digits that lead to fewer carries (balanced digits). These balanced systems turn out to be best (fewest carries). Showing this requires an excursion into additive combinatorics a la Gowers-Green-Szemeredi-Tao. This is joint work with Shao and Soundarajan.
