Characteristic classes for families of genus one curves
Tuesday, 22.01.2013 10:00 im Raum SR 1C
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.
