The RÃ©nyi entropy of the order of a random permutation

Adrian Beker

We study the distribution of the order of a random permutation of $[n]$ through the lens of RÃ©nyi entropy. In particular, we obtain an asymptotic for the RÃ©nyi $q$ -entropy of the…

The most probable order of a random permutation

Adrian Beker

Given positive integers $n$ and $m$ , let $p_{n} (m)$ be the probability that a uniform random permutation of $[n]$ has order exactly $m$ . We show that, as $n \to \infty$ , the maximum…

Limiting spectral laws for sparse random circulant matrices

Adrian Beker

Fix a positive integer $d$ and let $(G_{n})_{n \geq 1}$ be a sequence of finite abelian groups with orders tending to infinity. For each $n \geq 1$ , let $C_{n}$ be a uniformly random $G_…
