On sections of Lefschetz fibrations and bundles over 2-complexes
Jonathan A. Hillman, Riccardo Pedrotti
We address the question of existence of sections of fibrations in two settings. First, we show that a bundle with base a finite 2-complex admits a section if and only if the inclus…

Fixed point Floer cohomology of disjoint Dehn twists on a w+-monotone manifold with rational symplectic form
Riccardo Pedrotti
We give an explicit description of the Floer cohomology of a family of Dehn twists about disjoint Lagrangian spheres in a w+ - monotone rational symplectic manifold. As a byproduct…
