The Jacobian, the square root and the set ∞
speaker: Fabrice Bethuel (Laboratoire Jacques-Louis LIONs, Université Pierre et Marie Curie, Paris)abstract: We discuss the problem of prescribing the Jacobian determinant in dimension two: we restrict ourselves to the case the datum is a finite sum of Dirac masses with integer multiplicity. The main point here is to show that we may relate this problem to the search of harmonic maps into a singular space which is shaped as the symbol ∞ (or the number 8). The later problem in turn is closely linked to meromorphic functions. A large part of the presentation is devoted to a presentation of the various mathematical objets and their connections.
