A recording of a talk at Big Ideas in Dynamics in Geometry: A Hybrid Conference. The talk took place on September 27th, 2024 at UIC.

His talk will focus on lemma 2.1 from Strict Ergodicity and Transformation of the Torus by Hillel Furstenberg, leading into upcoming joint work with Bedaride, Hooper, and Hubert on the ergodicity of billiard flows in right-angled prisms

Helpful background for reading: Basic ergodic theory, and fourier analysis on the circle
