On foliated characteristic classes of transversally symplectic foliations
Jonathan Bowden
Kotschick and Morita recently discovered factorisations of characteristic classes of transversally symplectic foliations that yield new characteristic classes in foliated cohomolog…
On closed leaves of foliations, multisections and stable commutator lengths
Jonathan Bowden
We give examples of foliations that answer two questions posed by Mitsumatsu and Vogt about the genus minimising properties of closed leaves of 2-dimensional foliations on 4-manifo…
Flat structures on surface bundles
Jonathan Bowden
We show that there exist flat surface bundles with closed leaves having non-trivial normal bundles. This leads us to compute the Abelianisation of surface diffeomorphism groups wit…
The homology of surface diffeomorphism groups and a question of Morita
Jonathan Bowden
We answer a question posed by Morita concerning the non-triviality of certain secondary characteristic classes for surface bundles. In doing so we are naturally led to show that a…
