Abstract

The set of n by n upper-triangular nilpotent matrices with entries in a finite field F_q has Jordan canonical forms indexed by partitions λ ⊢ n. We study a connection between these matrices and non-attacking q-rook placements, which leads to a combinatorial formula for the number F_λ (q) of matrices of fixed Jordan type as a weighted sum over rook placements.
