Induced subgraphs of hypercubes and a proof of the Sensitivity Conjecture: In this paper, we show that every (2^{n-1}+1)-vertex induced subgraph of
the n-dimensional cube graph has maximum degree at least sqrt{n}. This
result is best possible, and improves a logarithmic lower bound shown by Chung,
Füredi, Graham and Seymour in 1988. As a direct consequence, we prove that
the sensitivity and degree of a boolean function are polynomially related,
solving an outstanding foundational problem in theoretical computer science,
the Sensitivity Conjecture of Nisan and Szegedy. Huang, Hao.
