Lie group action on manifold

Websubgroups” are precisely the salient feature of the group Zp which distinguishes it from a Lie group. It is also interesting to compare this observation with the result of Newman [18] (see also Smith [23] and Dress [4]) that nontrivial actions of compact Lie groups on manifolds cannot be arbitrarily C0-close to the trivial action.

Therefore the approaches can be used only for o -line applications concerned with construction of spline curves on smooth manifolds. The approach to construction of spline curves on smooth manifolds by action of Lie groups was introduced in [11]. WebDenote the Lie algebra of ν -linear derivations of * by . An action of a Lie group G on a star product * on a Poisson manifold (M, P) is a homomorphism ; then and there is an induced Poisson action τ of G on ( M, P ).
