The monopole h-invariants from a topological perspective
Stefan Behrens
We study the monopole h-invariants of 3-manifolds from a topological perspective based on Lidman and Manolescu's description of monopole Floer homology in terms of Seiberg-Witten-F…
Classification of boundary Lefschetz fibrations over the disc
Stefan Behrens, Gil R. Cavalcanti, Ralph L. Klaasse
We show that a four-manifold admits a boundary Lefschetz fibration over the disc if and only if it is diffeomorphic to , $\# m\mathbb{…
Heegaard Floer correction terms, with a twist
Stefan Behrens, Marco Golla
We use Heegaard Floer homology with twisted coefficients to define numerical invariants for arbitrary closed 3-manifolds equipped torsion spin structures, generalising the corr…
Elimination of cusps in dimension 4 and its applications
Stefan Behrens, Kenta Hayano
Several new combinatorial descriptions of closed 4-manifolds have recently been introduced in the study of smooth maps from 4-manifolds to surfaces. These descriptions consist of s…
On 4-Manifolds, Folds and Cusps
Stefan Behrens
We study simple wrinkled fibrations, a variation of the simplified purely wrinkled fibrations introduced by Williams, and their combinatorial description in terms of surface diagra…
