Journal ArticleDOI
From sets to functions: Three elementary examples
TL;DR: A totally combinatorial way of finding the change of basis matrix: to each pair of sequences is associated a poset whose Whitney numbers of the 1st and 2nd kind give the entries of the matrix and its inverse.
Journal ArticleDOI
A vector space analog of permutations with restricted position
S. A. Joni,Gian-Carlo Rota +1 more
Journal ArticleDOI
The multi-indexed partitional
TL;DR: The multi-indexed partitional is a generalization of the partitional of Foata and Schutzenberger, and gives a combinatorial interpretation for certain multivariate polynomial sequences of binomial type.
Journal ArticleDOI
Expansion formulas. I. A general method
TL;DR: In this article, the authors derived a bijection between a class of expansion formulas and Sheffer sequences of polynomials, and showed that these expanions follow as special cases.
Book ChapterDOI
On Restricted Bases for Finite Fields
S. A. Joni,G.-C. Rota +1 more
TL;DR: This chapter describes restricted bases for finite fields with some theorems and problems with its solution discussed in the chapter.
