Small Influential Coalitions in via the Junta Theorem

Ehud Friedgut

Every monotone Boolean function on the continuous cube admits a coalition of coordinates that can force a fixed output (either zero or one) with probabil…

Chvátal's conjecture: a proof from The Book

David Ellis, Yuval Filmus, Ehud Friedgut

Chvátal conjectured that every downset has a maximum-size intersecting family which is a star, that is, consists of all members of the downset containing a fixed element. Recently,…

The success probability in Levine's hat problem, and independent sets in graphs

Noga Alon, Ehud Friedgut, Gil Kalai +1

Lionel Levine's hat challenge has players, each with a (very large, or infinite) stack of hats on their head, each hat independently colored at random black or white. The playe…

Sharp thresholds for Ramsey properties

Ehud Friedgut, Eden Kuperwasser, Wojciech Samotij +1

In this work, we develop a unified framework for establishing sharp threshold results for various Ramsey properties. To achieve this, we view such properties as non-colourability o…

FKN, first proof, rewritten

Ehud Friedgut, GIl Kalai, Assaf Naor

About twenty years ago we wrote a paper, "Boolean Functions whose Fourier Transform is Concentrated on the First Two Levels", \cite{FKN}. In it we offered several proofs of the sta…
