- In mathematics,
anticommutativity is a
specific property of some non-commutative
mathematical operations.
Swapping the

- In
quantum field theory,
fermions are
described by
anticommuting spinor fields. A four-fermion
interaction describes a
local interaction between four...
- periodicity. We will need to
study anticommuting matrices (AB = −BA)
because in
Clifford algebras orthogonal vectors anticommute A ⋅ B = 1 2 ( A B + B A ) =...

there are also "

- a Gr****mann number,
named after Hermann Gr****mann (also
called an
anticommuting number or supernumber), is an

- Schwinger's

significant because it
could treat fermionic anticommuting fields with the same
formalism as bose fields, thus
implicitly introducing...
