Noncrossing partitions
2000
Discrete Mathematics
In a 1972 paper, Germain Kreweras investigated noncrossing partitions under the reÿnement order relation. His paper set the stage both for a wealth of further enumerative results, and for new connections between noncrossing partitions, the combinatorics of partially ordered sets, and algebraic combinatorics. Without attempting to give an exhaustive account, this article illustrates aspects of enumerative and algebraic combinatorics supported by the lattice of noncrossing partitions, re ecting
