Divergence free vector field on compact surface
Tes m'y question can be reformulate as follow: what is the asymptotic behaviour of harmonic one form when the conformal class degenerate? |

Elliptic regularity for two dimensional domains
Yes it is. If u=ln(ln(r)), then \nabla u \in L^2 but conclusion fails |

Gauss curvature flow
Is that clear, that the condition $\langle x, \nu \rangle=K$ is preserved? Else it looks good. |

harmonic extension of a curve by different parametrization
Thanks for the Answer. The first point was indeed "easy". In fact I know quite well the solution of Douglas-Rado (through Struwe's book). lik in lawson, he minimise the energy among conformal parametrisation. But since my goal is 3)(1) and 2) are a try to make more explicit), it can't be adapted here. If we consider $h:z\mapsto z+ z^2/4$ , $\vert h(\mathbb{D})\vert=9/8$, but $\vert h'(0)\vert=1$ and any conformal reparametrization(using mobius group) will be below $9/8$. |

Decomposition of a closed surface
yes I mean homotopy. have you a reference for the pants decomposition? because I need minimizing representant without intersection... who is Shepard?Thx |

Decomposition of a closed surface
Thanks for the answer. Can you give me more references. Notably,about the theorem you invoke. it is not totally clear to me since an homology class is like a open cylinder, and without the negative curvature assumption, perhaps the minimum is not achieved? And I didn't also find a Shepard at UCB... Thanks again for your help!! |
