„Characteristic classes for families of genus one curves“
Prof. Lenny Taelman, Universität Leiden
I will show how to (partly) compute the cohomology of the stack of genus one curves, and how this yields a rich source of cohomological invariants (`characteristic classes') of families of curves of genus one. In particular, these invariants give non-trivial obstructions against the existence of a section.
