Real algebraic actions on projective spaces - A survey
Let be a compact lie group. We introduce the set for every smooth manifold . It consists of equivalence classes of pair where is a map which defines a homotopy equivalence from to . Two pairs , for , are equivalent if there is a homotopy equivalence such that is homotopic to .Properties of the set and related to the representation of on the tangent spaces of and at the fixed points. For the case and is the manifold defined by a “linear” action on complex...
