An equivalence between a conjecture of Neumann-Praeger on Kronecker classes and a conjecture on cliques of derangement graphs

Jessica Anzanello, Pablo Spiga

We prove an equivalence between a conjecture of Neumann and Praeger on Kronecker classes in algebraic number fields, and a conjecture on cliques of derangement graphs in combinator…

On the proportion of derangements in affine classical groups

Jessica Anzanello

We derive exact formulas for the proportions of derangements and of derangements of $p$ -power order in the affine classical groups $A U_{m} (q)$ , $A S p_{2 m} (q)$ , $A O_{2 m + 1} (q)$ and $AO^…
