The Robust Thompson's Conjecture for Alternating Groups

Nathan Keller, Noam Lifshitz, Avichai Marmor +1

We show that there exists a constant $ε > 0$ such that if $C$ is a conjugacy class in $A_{n}$ of size at least $∣ A_{n} ∣^{1 - ε}$ , then $A_{n} ∖ {1} \subseteq C^{2}$ . This proves the…

On Shalev's Quantitative Version of Thompson's Conjecture

Ohad Sheinfeld

The classical Thompson's conjecture asserts that in any finite nonabelian simple group $G$ , there exists a conjugacy class $S$ whose square is equal to the entire group. Shalev (An…

Improved covering results for conjugacy classes of symmetric groups via hypercontractivity

Nathan Keller, Noam Lifshitz, Ohad Sheinfeld

We study covering numbers of subsets of the symmetric group $S_{n}$ that exhibit closure under conjugation, known as \emph{normal} sets. We show that for any $ε > 0$ , there exists $n_0…
