WebJan 14, 2024 · Left invariant framings on compact connected Lie groups Idea In one sense of the term, a framingof a manifoldis a choice of trivialization of its tangent bundle, hence a choice of sectionof the corresponding frame bundle. A manifold that admits a framing is also called a parallelizable manifold. WebApr 23, 2024 · In Lie theory. In Lie theory, a Weyl group is a group associated with a compact Lie group that can either be abstractly defined in terms of a root system or in terms of a maximal torus. More generally there are Weyl groups associated with symmetric spaces. The Weyl group of a compact Lie group G is equivalently the quotient group of the ...

WebIn mathematics, a Lie groupoid is a groupoid where the set of objects and the set of morphisms are both manifolds, all the category operations (source and target, composition, identity-assigning map and inversion) are smooth, and the source and target operations ,: are submersions.. A Lie groupoid can thus be thought of as a "many-object generalization" of … WebThe three maps above are canonical with respect to the Lie group structure. Therefore all tangent spaces of G are canonically isomorphic. For g,h ∈ G, we have the canonical linear isomorphisms T g(L hg−1): T gG ... is a smooth manifold with tangent bundle GL(T eG) × gl(T eG). Therefore the tangent map of Ad at the identity e is a map T eAd ...
