Normal form of equivariant maps in infinite dimensions
Tobias Diez, Gerd Rudolph
Local normal form theorems for smooth equivariant maps between infinite-dimensional manifolds are established. These normal form results are new even in finite dimensions. The proo…

Slice theorem and orbit type stratification in infinite dimensions
Tobias Diez, Gerd Rudolph
We establish a general slice theorem for the action of a locally convex Lie group on a locally convex manifold, which generalizes the classical slice theorem of Palais to infinite…
