Explicit expressions and integral representations for the Stirling numbers. A probabilistic approach

Abstract: We show that the Stirling numbers of the first and second kind can be represented in terms of moments of appropriate random variables. This allows us to obtain, in a unified way, a variety of old and new explicit expressions and integral representations of such numbers.

“…To show Theorem 1, we use a probabilistic representation of S(n, k) by means of a multinomial law, which is close to the classical representation in terms of occupancy problems (see Pitman [9] for more details). Indeed, we give in Theorem 2 (the main result in this note) a closed form expression for the difference S(n, k) − S(n, k − 1) in terms of multinomial probabilites and the function g n (x) defined in (1). This allows us to characterize Wegner's conjecture on the one hand and to give a short proof of Theorem 1, on the other.…”

“…Unless otherwise stated, we assume from now on that n, k ∈ N. Let (U j ) j≥1 be a sequence of independent identically distributed random variables having the uniform distribution on [0, 1]. Sun [11] (see also [1]) gave the following probabilistic representation…”
