In physics, the Pauli exclusion principle (Pauli 25) states that no two spinors may inhabit the same quantum state. This is a consequence of the spin-statistics theorem, which states that spinors must be fermions.

Mathematically this is the statement that fermion fields are the odd-graded elements of a superalgebra of functions in supergeometry.

The Pauli exclusion principle implies that fermions, as opposed to bosons, may form solid bodies that do not necessarily collapse under their own gravity (as opposed to bosonic condensates): the exclusion principle induces an outward pressure?, the degeneracy pressure (see also at Fermi sea? and neutron star). It is used in the explanation of the stability of matter of the second kind.
