Establishing (and oftentimes, even formulating) structural results for Boolean functions with respect to some problem of interest is prevalent throughout many branches of mathematics. A prominent example is the “structure versus randomness” paradigm. Notable problems that were recently solved, using such ideas, include the quantitative improvement of the sunflower lemma, advances on various Turán problems, the resolutions of the sensitivity conjecture, the cap set problem, and the Kahn-Kalai Conjecture. The goal of this workshop is to bring together researchers from different perspectives, introduce the different techniques in these problems and push them further.
