An Explicit Formula for the Number of Solutions of X^2=0 in Triangular Matrices over a Finite Field

Shalosh B. Ekhad, Doron Zeilberger

Published 1995-12-19Version 1

We prove an explicit formula for the number of $n \times n$ upper triangular matrices, over $GF(q)$, whose square is the zero matrix. This formula was recently conjectured by Sasha Kirillov and Anna Melnikov[KM].
