High Quality Content by WIKIPEDIA articles! In mathematics, the n! conjecture is the conjecture that the dimension of a certain bi-graded module of diagonal harmonics is n!. It was made by A. M. Garsia and M. Haiman and later proved by M. Haiman. It implies Macdonald's positivity conjecture about his Macdonald polynomials. The Macdonald polynomials P are a two-parameter family of orthogonal polynomials indexed by a positive weight of a root system, introduced by Ian G. Macdonald (1987).

Garsia and M. Haiman and later proved by M. Haiman. It implies Macdonald's positivity conjecture about his Macdonald polynomials. The Macdonald polynomials P are a two-parameter family of orthogonal polynomials indexed by a positive weight of a root system, introduced by Ian G. Macdonald (1987). They generalize several other families of orthogonal polynomials, such as Jack polynomials and Hall Littlewood polynomials. They are known to have deep relationships with affine Hecke algebras and Hilbert schemes, which were used to prove several conjectures made by Macdonald about them.
