Some Identities Involving Derangement Polynomials and Numbers and Moments of Gamma Random Variables

The problem of counting derangements was initiated by Pierre Rémond de Montmort in 1708. A derangement is a permutation that has no fixed points, and the derangement number Dn is the number of fixed point free permutations on an n element set. Furthermore, the derangement polynomials are natural ext...
