Title: Constructions of symplectic fillings

 Abstract:  Bourgeois constructed a family of contact structures on $M \times T^2$ if $M$ is contact, using Giroux’s open book decomposition.

We will see that these are very sensitive to the page of the open book, but less so to the monodromy. We will also see that many of these are weakly fillable, by a family of constructions. This is partially joint work with Marinkovic and Niederkrüger.
