The problem that we are concerned with is the existence and construction of embeddings of a given G-CW complex (G-manifold) in another G-CW complex (G-manifold) having a prescribed homotopy type and a prescribed family of isotropy subgroups.

The purpose of this paper is to study the following problem: When is there a locally flat embedding g: N[superscript]n [right arrow] M[superscript]m such that pg is [lowercase Greek]Alpha-close to h? This problem is intimately related to the problem of approximating topological …
"This book presents a geometric introduction to the homology of topological spaces and the cohomology of smooth manifolds. The author introduces a new class of stratified spaces, so-called stratifolds. He derives basic concepts from differential topology such as Sard's theorem, …
