On the Relative Dualising Sheaf of a Symplectic Lefschetz Fibration

چکیده
For the dualising sheaf ωX/B of a relatively minimal symplectic Lefschetz fibration π : X → B, we show that c21(ωX/B) ≥ 0. Some consequences related to the Hodge bundle are obtained.

Lefschetz Fibrations and 3-fold Branched Covering Spaces, Ii
Let M be a smooth 4-manifold which admits a relatively minimal genus h Lefschetz fibration over S, and assume that the collection of vanishing cycles for this fibration includes σ separating curves. For h ≥ 3, we show that M is the relative minimalization of a genus h Lefschetz fibration obtained as an irregular simple 3-fold branched cover of the rational surface CP #(2σ + 1)CP , branched over...
متن کاملSymplectic Lefschetz Fibrations on S ×m
A remarkable theorem of Donaldson [D] says that a symplectic 4manifold admits a Lefschetz pencil by symplectic surfaces. Given a Lefschetz pencil on a 4-manifold X, one can blow up points at the base locus to get a Lefschetz fibration of X over S, which admits a nice handlebody decomposition and can be described by geometric monodromy representation into the mapping class group of a regular fib...
متن کاملLefschetz Fibration Structures on Knot Surgery 4-manifolds
In this article we study Lefschetz fibration structures on knot surgery 4-manifolds obtained from an elliptic surface E(2) using Kanenobu knots K. As a result, we get an infinite family of simply connected mutually diffeomorphic 4-manifolds coming from a pair of inequivalent Kanenobu knots. We also obtain an infinite family of simply connected symplectic 4-manifolds, each of which admits more t...
متن کاملLegendrian Realization in Convex Lefschetz Fibrations and Convex Stabilizations
In this paper, we study compact convex Lefschetz fibrations on compact convex symplectic manifolds (i.e., Liouville domains) of dimension 2n + 2 which are introduced by Seidel and later also studied by McLean. By a result of Akbulut-Arikan, the open book on ∂W , which we call convex open book, induced by a compact convex Lefschetz fibration on W carries the contact structure induced by the conv...
متن کاملOn the Holomorphicity of Genus Two Lefschetz Fibrations
We prove that any genus-2 Lefschetz fibration without reducible fibers and with “transitive monodromy” is holomorphic. The latter condition comprises all cases where the number of singular fibers μ ∈ 10N is not congruent to 0 modulo 40. An auxiliary statement of independent interest is the holomorphicity of symplectic surfaces in Sbundles over S, of relative degree ≤ 7 over the base, and of sym...
