Title
Restricted Stirling and Lah number matrices and their inverses.
Abstract
Given R⊆N let {nk}R, [nk]R, and L(n,k)R count the number of ways of partitioning the set [n]:={1,2,…,n} into k non-empty subsets, cycles and lists, respectively, with each block having cardinality in R. We refer to these as the R-restricted Stirling numbers of the second kind, R-restricted unsigned Stirling numbers of the first kind and the R-restricted Lah numbers, respectively. Note that the classical Stirling numbers of the second kind, unsigned Stirling numbers of the first kind, and Lah numbers are {nk}={nk}N, [nk]=[nk]N and L(n,k)=L(n,k)N, respectively.
