Daniel Greb (Universität Duisburg-Essen) to speak in the geometry seminar, tuesday 17 March.

Daniel Greb (Universität Duisburg-Essen) will speak in the geometry seminar on Tuesday 17 March 2020 at 11h am in the Salle des Profs. Daniel’s title is Projectively flat sheaves and characterisations of finite quotients of projective spaces and his abstract is below.

I will explain how to extend the classical characterisation of projective space among Kähler-Einstein Fano manifolds in terms of a Chern class (in)equality to the class of Fano varieties with Kawamata log terminal singularities. I will spend significant time on discussing the necessary tools, which range from analysis (harmonic metrics / Simpson correspondence) and classical differential geometry to algebraic geometry (local fundamental groups of klt singularities). This is joint work with Stefan Kebekus and Thomas Peternell, and partly with Behrouz Taji.

Getting here

The department of mathematics is in building NO, on the Campus de la Plaine, of the Université libre de Bruxelles. The geometry group is on the 7th floor. This map shows NO, as well as the metro station Delta and entrance 2, which is right by the stop for the number 71 and 72 buses. The number 95 also stops a short walk from the department. See the STIB website for more information on public transport in Brussels.
