Macdonald identities

Template:Short description In mathematics, the Macdonald identities are some infinite product identities associated to affine root systems, introduced by Template:Harvs. They include as special cases the Jacobi triple product identity, Watson's quintuple product identity, several identities found by Template:Harvtxt, and a 10-fold product identity found by Template:Harvtxt.

Template:Harvtxt and Template:Harvtxt pointed out that the Macdonald identities are the analogs of the Weyl denominator formula for affine Kac–Moody algebras and superalgebras.
