Can we foliate the punctured space by tori?
I would like to offer another explanation of the impossibility of foliating $R^3-0$ by tori (or by higher genus closed surfaces), at least in the $C^\infty$ case.
Previously I commented that "folia …

Fundamental groups of noncompact surfaces
A new approach to spines is available via mass transport theory and Kantorovich duality. This is developed in my PhD thesis.
The idea is elementary: consider the retract $x\mapsto x/|x|$ from the cl …

Is there a homotopy/homology-theory for probability spaces?
The question needs be expressed in categorical terms.
The category of topology $TOP$ consists of objects and morphisms being topological spaces and continuous maps, respectively. Homology and homotopy …
