First Friday Math Seminar

Simons Rock alum Ethan Ackelsberg (Ohio State University) joins us in our monthly seminar to present his talk, "From the pigeonhole principle to ergodic Ramsey theory."

Ramsey theory is a branch of combinatorics based on the widespread phenomenon that certain mathematical structures (e.g., arithmetic progressions, complete graphs, convex polygons) inevitably appear on a large enough scale. Ergodic theory involves the study of the long-term statistical behavior of dynamical systems. Surprisingly, these two areas are connected in very deep ways. We will give a sampling of the amazing connections between ergodic theory and Ramsey theory, starting from one of the simplest results in all of mathematics: the pigeonhole principle.
