Jun 15, 2014 at 4:20	comment	added	Włodzimierz Holsztyński		My private library is mostly gone, and I don't have a convenient access to a real mathematical library. I remember that one of the Borsuk major topological topics was the uniqueness of the topological cartesian decomposition. Later a remarkable paper about the uniqueness of the decomposition of finite-dimensional ANRs into the 1-dimensional factors (and a finite space) was written H. Patkowska--a student of Borsuk. Borsuk himself considered, among other things, the decomposition of manifolds into a manifold and a 1-dimensional factor (I don't remember more, so sorry).

Jun 13, 2014 at 5:31	comment	added	Włodzimierz Holsztyński		Could one relate the respective Karol Borsuk papers from the past to this topic?

Mar 29, 2013 at 22:18	comment	added	J. GE		@Mark, Yes they are compact and hence closed. I don't impose smoothness here since I mainly interested in topological category.
Mar 29, 2013 at 22:14	comment	added	Mark Grant		Are $M$ and $N$ assumed to be closed? smooth?
