»Hyperkähler manifolds and their automorphisms«

Andre Weil In 1958 gave the name ”K3 surfaces” to a class of smooth and simply connected complex surfaces, with trivial canonical bundle and such that their tangent space in each point is endowed with a non-degenerate and symplectic two form. These surfaces became more and more important during the last fifty years and in the 80’s Fujiki and Beauville discovered examples of manifolds with the same properties but in higher dimensions, the so called Hyperkähler manifolds. In this talk I have in aim to give you an introduction to them, which are one of the building blocks in the classification of compact complex surfaces with trivial first Chern class. Moreover I will introduce automorphisms of these manifolds and I will give you a classification in the OG6 case, where OG6 is a specific deformation type in dimension six.


Hierzu ergeht herzliche Einladung.
