Casimir invariant

In mathematics, a Casimir invariant or Casimir abettor is a acclaimed aspect of the centre of the accepted enveloping algebra of a Lie algebra. A prototypal archetype is the boxlike angular drive operator, which is a Casimir invariant of the three-dimensional circling group.

The Casimir invariant is called afterwards Hendrik Casimir, who articular them in his description of adamant anatomy dynamics in 1931.
