I am a temporary professor for mathematics at the Justus-Liebig Universität Gießen for the winter term 2024/2025.
Informationen zum Wintersemester 2024/2025 an der JLU Gießen.
3rd Marburger Arbeitsgemeinschaft Mathematik (MAM)
Each Marburger Arbeitsgemeinschaft Mathematik has as topic an important unsolved question in pure mathematics, with the aim of giving the participants a complete picture of its state of the art. No speakers are invited; instead, the participants of the workshop can apply for a talk.
In its third installment, we will discuss classical and recent results on the geometry and topology of quaternion-Kähler manifolds, with a particular emphasis on results in the vicinity of the LeBrun-Salamon conjecture, stating that every quaternion-Kähler manifold with positive scalar curvature is symmetric, i.e., a Wolf space. The first talks of the meeting will give an introduction to quaternion-Kähler geometry.
