Abstract:

Ancel’s method of fiberwise trivial relations is applied to the problem of characterization of absolute equivariant extensors. We obtain a generalization of Jaworowski’s theorem on characterization of equivariant extensors lying in $\mathbb {R}^{n}$ to the case when the space is infinite-dimensional, has infinitely many orbit types and the acting compact group $G$ is not necessarily a Lie group.
