Title: "Almost commuting permutations are near commuting
Speaker: Liviu Paunescu (IMAR, Bucharest)
Abstract: We prove that the commutator is stable in permutations endowed with the Hamming
distance, that is, two permutations that almost commute are near two commuting permutations.
Our result extends to \(k\)-tuples of almost commuting permutations, for any given \(k\), and
allows restrictions, for instance, to even permutations.
