How to realize a Lie algebra by vector fields
I. M. Shchepochkina Independent University of Moscow
Abstract:
We describe an algorithm for embedding a finite-dimensional Lie algebra
(superalgebra) into a Lie algebra (superalgebra) of
vector fields that is suitable for a ground field of any characteristic and
also a way to select the Cartan, complete, and partial prolongations of the
Lie algebra of vector fields using differential equations. We illustrate the
algorithm with the example of Cartan's interpretation of the exceptional
simple Lie algebra $\mathfrak g(2)$ as the Lie algebra preserving a certain
nonintegrable distribution and also several other examples.
Keywords:
Cartan prolongation, nonintegrable distributions, $\mathfrak g(2)$ structure.
