Sandpile groups of random bipartite graphs and families of distributions with the same moments

Jason Fulman, Nathan Kaplan, Deepesh Singhal +1

Recently, there has been significant interest in applying the method of moments developed by Wood and others to study distributions of finite abelian groups that arise in number th…

Stein's method and the modular behavior of Eulerian numbers

Jason Fulman, Adrian Röllin

The Eulerian number A(n,k) counts permutations of n symbols with exactly k descents. Motivated by problems in cryptography, several authors have studied the proportion of permutati…

Derangements in affine classical groups and Cohen-Lenstra heuristics

Jason Fulman, Dennis Stanton

We observe that Anzanello's work on the proportion of derangements in affine classical groups over finite fields is related to symplectic and orthogonal Cohen-Lenstra type distribu…

Derangements in finite classical groups and characteristic polynomials of random matrices

Jason Fulman, Robert Guralnick

We first obtain explicit upper bounds for the proportion of elements in a finite classical group G with a given characteristic polynomial. We use this to complete the proof that th…

Fixed points of non-uniform permutations and representation theory of the symmetric group

Jason Fulman

We use representation theory of the symmetric group S_n to prove Poisson limit theorems for the distribution of fixed points for three types of non-uniform permutations. First, we…

Probabilistic Generation of Finite Almost Simple Groups

Jason Fulman, Daniele Garzoni, Robert M. Guralnick

We prove that if G is a sufficiently large finite almost simple group of Lie type, then given a fixed nontrivial element x in G and a coset of G modulo its socle, the probability t…
