Lefschetz Fibrations on Compact Stein Manifolds Selman Akbulut and M. Firat Arikan

چکیده
Here we prove that a compact Stein manifoldW 2n+2 of dimension 2n+2 > 4 admits a Lefschetz fibration over the disk D with Stein fibers, such that the monodromy of the fibration is a symplectomorphism induced by compositions of “generalized Dehn twists” along imbedded n-spheres on the generic fiber. Also, the open book on the boundary ∂W , which is determined by the fibration, is compatible with the contact structure induced by the Stein structure. This generalizes the Stein surface case of n = 1, previously proven by Loi-Piergallini and Akbulut-Ozbagci.

Legendrian 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 کاملStabilizations via Lefschetz Fibrations and Exact Open Books Selman Akbulut and M. Firat Arikan
We show that if a contact open book (Σ, h) on a (2n+1)-manifoldM (n ≥ 1) is induced by a Lefschetz fibration π : W → D, then there is a one-to-one correspondence between positive stabilizations of (Σ, h) and positive stabilizations of π. More precisely, any positive stabilization of (Σ, h) is induced by the corresponding positive stabilization of π, and conversely any positive stabilization of ...
متن کاملLefschetz Fibrations on Compact Stein Manifolds
Here we prove that up to diffeomorphism every compact Stein manifold W of dimension 2n + 2 > 4 admits a Lefschetz fibration over the disk D with Stein regular fibers, such that the monodromy of the fibration is a symplectomorphism induced by compositions of right-handed Dehn twists along embedded Lagrangian n-spheres on the generic fiber. This generalizes the Stein surface case of n = 1, previo...

We show that for each k > 3 there are infinitely many finite type Stein manifolds diffeomorphic to Euclidean space R which, as symplectic manifolds are pairwise not symplectomorphic to each other.
متن کاملCoassociative K3 Fibrations of Compact G2-manifolds
A class of examples of Riemannian metrics with holonomy G2 on compact 7-manifolds was constructed by the author in [Ko] using a certain ‘generalized connected sum’ of two asymptotically cylindrical manifolds with holonomy SU(3). We consider, on each of the two initial SU(3)-manifolds, a fibration arising from a Lefschetz pencil of K3 surfaces. The gluing of the two K3 fibrations yields a coasso...
