Universität Konstanz Fachbereich Mathematik und Statistik Schwerpunkt Reelle Geometrie und Algebra Einladung Im Oberseminar Reelle Geometrie und Algebra hält Tomas Bajbar (Karlsruher Institut für Technologie) am Freitag, 17.06.2016, einen Vortrag zum Thema: On Globally Diffeomorphic Polynomial Maps via Newton Polytopes and Circuit Numbers Der Vortrag findet um 13:30 Uhr in F426 statt. Alle Interessenten sind herzlich eingeladen. Abstract: In this article we analyze the global diffeomorphism property of polynomial maps F : Rn → Rn by studying the properties of the Newton polytopes at infinity corresponding to the sum of squares polynomials kF k22 . This allows us to identify a class of polynomial maps F for which their global diffeomorphism property on Rn is equivalent to their Jacobian determinant det JF vanishing nowhere on Rn . In other words, we identify a class of polynomial maps for which the Real Jacobian Conjecture, which was proven to be false in general, still holds. Sebastian Gruler Koordinator Oberseminar
