Explore structure theorems in Boolean Function Analysis through this lecture by Yuval Filmus at the Hausdorff Center for Mathematics. Delve into classical theorems such as the FKN theorem and Friedgut's junta theorem, as well as modern developments in the field. Focus on applications to the biased hypercube and the symmetric group while gaining insights into sharp threshold theorems. Over the course of an hour, expand your understanding of Boolean Harmonic Analysis and its fundamental structural components.
