Appendix: Lefschetz Pencils with Imposed Subvarieties
نویسنده
چکیده
In this appendix, which is entirely expository, we give some basic facts about the existence of Lefschetz pencils with imposed subvarieties. These facts are certainly well known to the experts, but we are unaware of a suitable reference. We thank de Caltaldo and Kollar for a very helpful conversation.

The Zariski-lefschetz Principle for Higher Homotopy Groups of Nongeneric Pencils
We prove a general Zariski-van Kampen-Lefschetz type theorem for higher homotopy groups of generic and nongeneric pencils on singular open complex spaces.
متن کاملLefschetz pencils and divisors in moduli space
We study Lefschetz pencils on symplectic four-manifolds via the associated spheres in the moduli spaces of curves, and in particular their intersections with certain natural divisors. An invariant defined from such intersection numbers can distinguish manifolds with torsion first Chern class. We prove that pencils of large degree always give spheres which behave “homologically” like rational cu...

متن کاملLefschetz pencils and the canonical class for symplectic 4-manifolds
We present a new proof of a result due to Taubes: if (X,ω) is a closed symplectic four-manifold with b+(X) > 1 + b1(X) and λ[ω] ∈ H (X;Q) for some λ ∈ R, then the Poincaré dual of KX may be represented by an embedded symplectic submanifold. The result builds on the existence of Lefschetz pencils on symplectic four-manifolds. We approach the topological problem of constructing submanifolds with ...
متن کاملFukaya A∞-structures associated to Lefschetz fibrations. II
Consider the Fukaya category associated to a Lefschetz fibration. It turns out that the Floer cohomology of the monodromy around∞ gives rise to natural transformations from the Serre functor to the identity functor, in that category. We pay particular attention to the implications of that idea for Lefschetz pencils.
