Analysis of Boolean Functions at CMU - Lecture 18: The Hypercontractivity Theorem

From a channel Lumen includes in full: This is a CMU professor's channel of full university course lectures (complexity, quantum computing, Boolean function analysis, TCS toolkit) and research talks. Every sampled transcript is rigorous chalkboard or slide teaching with no entertainment framing. The only outliers are the 4-minute non-academic 'Final Prize Pantry (no quantum)' clip and one short with a clickbait-style title ('The secret GCD method they didn't teach you in school'), and both are caught by title patterns.

A 78-minute video from Ryan O'Donnell's catalogue; the title names its topic.
