Quandles and Lefschetz Fibrations
We show that isotopy classes of simple closed curves in any oriented surface admit a quandle structure with operations induced by Dehn twists, the Dehn quandle of the surface. We further show that the monodromy of a Lefschetz fibration can be conveniently encoded as a quandle homomorphism from the knot quandle of the base as a manifold with a codimension 2 subspace (the set of singular values) ...
متن کاملLefschetz Fibrations in Symplectic Geometry
One of the cornerstones of complex geometry is the link between positivity of curvature and ampleness. Let X be a compact complex manifold and L ! X be a holomorphic line bundle over X. Suppose that L has a unitary connection whose curvature form is ?2i! where ! is a positive (1; 1)-form on X. Then for large k the line bundle L k has many holomorphic sections. More precisely, the holo-morphic s...
متن کاملUnimodular Invariants of Totally Real Tori In
We study the global invariants of real analytic manifolds in the complex space with respect to the group of holomorphic unimodular transformations. We consider only totally real manifolds which admits a certain fibration over the circle. We find a complete set of invariants for totally real tori in Cn which are close to the standard torus. The invariants are obtained by an analogous classificat...
متن کاملLefschetz Fibrations and Symplectic Homology
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 کاملLefschetz Fibrations of 4-Dimensional Manifolds
An n-dimensional manifold is an object which locally resembles n-dimensional Euclidean space. Different categories of manifolds can be considered simply by requiring different sorts of maps to perform these local identifications: A manifold may be smooth (if the maps are required to be infinitely differentiable), or complex (if n is even and the maps are required to be holomorphic), or topologi...
