2022 Research Briefings: Bryna R. Kra, Northwestern University

Dynamical Approaches to Combinatorial Problems
Bryna R. Kra, Sarah Rebecca Roland Professor of Mathematics, Northwestern University

A fundamental question in mathematics is when objects have rigid structure and when they are completely disordered. Kra studies this question in the context of dynamical systems, describing invariants that characterize long term changes in a system. While these results describe the evolution of mathematical systems, Kra uses them to show the existence of structures in seemingly static problems and proves that certain infinite patterns exist in any sufficiently large subset of integers. Elected in 2019, Kra represents the Academy's section on Mathematics.
