Malcev algebra
In mathematics, a Malcev algebra (or Maltsev algebra or Moufang–Lie algebra) over a field is a (nonassociative) algebra that is antisymmetric, so that
- xy = −yx
and satisfies the Malcev identity
- (xy)(xz) = ((xy)z)x + ((yz)x)x + ((zx)x)y.
They were first defined by Anatoly Maltsev (1955).
Examples
- Any Lie algebra is a Malcev algebra.
- Any alternative algebra may be made into a Malcev algebra by defining the Malcev product to be xy − yx.
- The imaginary octonions form a 7-dimensional Malcev algebra by defining the Malcev product to be xy − yx.
