Fixed point subalgebras of Weil algebras: from geometric to algebraic questions
arXiv:1011.2394
Abstract
The paper is a survey of some results about Weil algebras applicable in differential geometry, especially in some classification questions on bundles of generalized velocities and contact elements. Mainly, a number of claims concerning a form of fixed points subalgebras of various Weil algebra is demonstrated.
