Extended Bell and Stirling Numbers from Hypergeometric Exponentiation
by
J.-M. Sixdeniers, K. A. Penson and A. I. Solomon
ABSTRACT:
Exponentiating the hypergeometric series 0FL(1,1,...,1;z), L = 0,1,2,..., furnishes a recursion rel
ation for the members of certain
integer sequences bL(n), n = 0,1,2,.... For L >= 0, the bL(n)'s are generalizations of the conventi
onal Bell numbers, b0(n). The corresponding
associated Stirling numbers of the second kind are also investigated. For L = 1 one can give a comb
inatorial interpretation of the numbers
b1(n) and of some Stirling numbers associated with them. We also consider the L>1 analogues of Bell
numbers for restricted partitions.
