Sensitivity Conjecture and Its Applications
Offered By: Simons Institute via YouTube
Course Description
Overview
Explore the groundbreaking resolution of the Sensitivity Conjecture in theoretical computer science through this illuminating lecture. Delve into the background of various complexity measures for Boolean functions and understand why the Sensitivity Conjecture remained a mystery for nearly 30 years. Follow a step-by-step explanation of the linear algebraic proof based on the Gotsman-Linial reduction, which solved this long-standing problem. Gain insights into the significance of this breakthrough, its historical context, and the best bounds and separations previously known. Examine the Gotsman-Linial equivalence, upper and lower bounds, and the main theorem. Learn about eigenvalue interlacing, signed adjacency matrices, and the innovative approach used in the 6-page paper that cracked the conjecture. Conclude by exploring corollaries, extensions, and exciting future research problems in this field of theoretical computer science.
