The postulate that electrons must be described by wavefunctions which are antisymmetric
with respect to interchange of the coordinates (including spin) of a pair of electrons.
A corollary of the principle is the Pauli exclusion principle
. All particles with half-integral spin (fermions) are described by antisymmetric
wavefunctions, and all particles with zero or integral spin (bosons) are described
by symmetric wavefunctions.
