ABSTRACT

There is a well-known procedure induction for extending an action of a subgroup H  of a Lie group G  on a topological space X  to an action of G  on an associated space. Induction can also extend a smooth action of a subgroup H  of a Lie group G  on a manifold M  to a smooth action of G  on an associated manifold. In this paper elementary methods are used to show that induction also works in the category of (nonsingular) real algebraic varieties and regular or entire maps if G  is a compact Abelian Lie group.
