|Time/Room:||3:30pm - 4:30pm/S-101|
We produce examples of non-trivial Hamiltonian fibrations that are not detected by previous methods (the characteristic classes of Reznikov for example), and improve theorems of Reznikov and Spacil on cohomology-surjectivity to the level of classifying spaces. Joint work with Yasha Savelyev.
