A Wonderful Paper by Igor Pak: Complexity Problems in Enumerative Combinatorics
Greetings from Sa Pa in the very north of Vietnam. Let me recommend a great thought-provoking paper by Igor Pak: Complexity problems in enumerative combinatorics. As Igor wrote on his blog: Well, I finally finished my ICM paper. It’s only 30 … Continue reading
Frankl’s Conjecture for Large Families: Ilan Karpas’ Proof
Frankl’s conjecture asserts that a for every finite family of of finite sets that is closed under union, there is an element that belongs to at least half the sets in the family. We mentioned the problem in our very … Continue reading
