Aasa Feragen

Hanner's theorem is a classical theorem in the theory of retracts and extensors in topological spaces, which states that a local ANE is an ANE. While Hanner's original proof of the…

Equivariant embedding of metrizable $G$ -spaces in linear $G$ -spaces

Aasa Feragen

Given a Lie group $G$ we study the class $\M$ of proper metrizable $G$ -spaces with metrizable orbit spaces, and show that any $G$ -space $X \in \M$ admits a closed $G$ -embedding int…
