Summer School "Generalized Curvature"

Over the last few decades, there has been intense research on various notions of curvature for non-smooth spaces. The aim of this school is to introduce some aspects of generalized curvatures on metric spaces, graphs, and polyhedra.
The following subjects will be covered: Lipschitz-Killing curvatures, discrete conformal maps, spectral theory of graphs, metric spaces with bounded curvature and surfaces with bounded integral curvature in the sense of Alexandrov. Besides the main courses, several talks by researchers active in the domain of the school will be given.
The target audience for this school are PhD students and postdocs interested in geometry and related subjects. Due to its broad scope the school might also attract some senior researchers.
For more detailed information (including registration) see the web page of the school.
