In mathematics, Young's lattice is a partially ordered set and a lattice that is formed by all integer partitions. It is named after Alfred Young, who in a series of papers On quantitative substitutional analysis developed representation theory of the symmetric group. In Young's theory, the objects now called Young diagrams and the partial order on them played a key, even decisive, role. Young's lattice prominently figures in algebraic combinatorics, forming the simplest example of a differential poset in the sense of Stanley (1988). It is also closely connected with the crystal bases for affine Lie algebras.

Famous quotes containing the word young:
“It does change the age that is young, once in Paris it was twenty-six, then it was twenty-two, then it was nineteen and now it is between thirty and forty. They tell about a new young man, how old is he you say and they say he is thirty.”
—Gertrude Stein (1874–1946)
