The algebra and geometry of ordered set partitions

An {\em ordered set partition} of size $n$ is a sequence $(B_1, \dots, B_k)$ of nonempty sets such that we have a disjoint union decomposition $B_1 \sqcup \cdots \sqcup B_k = \{1, 2, \dots, n \}$.  When $k = n$, we have a natural identification with permutations in the symmetric group $S_n$. We discuss algebraic and geometric incarnations of ordered set partitions, generalizing results of Chevalley, Artin, Steinberg, Borel, and others. We also discuss how ordered set partitions relate to the theory of Macdonald polynomials.
