Reference/proof for parabolic Holder spaces property
Thanks. In Krylov book mentioned there such property is given as an exercise. I am going for a crash course in parabolic Holder spaces... |

Topology of ${\mathbb R}^n$
@Sam/Wlodzimierz - After your (Sam) comment on contractibility, it seems to me that the point is exactly that... the problem can also be reduced to show that a compact $(n-1)$-dimensional submanifold embedded in ${\mathbb R}^n$ cannot be retracted (in itself) on some ${\mathbb S}^m$, with $m\leq n-2$ ($m$ is actually the dimension of the factor N minus 1). I am wondering whether the fact that the hypersurface "disconnects" ${\mathbb R}^n$ and the "final" sphere ${\mathbb S}^m$ instead does not, can be used (at least in the differential case) to get a conclusion without using (co)-homology. |

Topology of ${\mathbb R}^n$
I had in mind something in this spirit. I was just wondering if it was possible something easier, the question came from one of my undergraduate students. |

analysis of the regularity using Hormander condition
Possibly, you should say in what spaces you are looking for uniqueness/regularity/continuous dependence |
