Description
(Fabrice Bethuel - Sorbonne University)
The purpose of the talk is to present a few problems and some results concerning the existence and properties of maps from a puncture plane with values in a one-dimensional singular manifold. A typical example is given by the "eight-shaped" manifold, which will be central in the talk. I will present some new results obtained in the thesis of Mehdi Trense, in particular how they convert the problems as questions on Riemann surfaces.
