The E8–manifold, singular fibers and handlebody decompositions
نویسندگان
چکیده
The E8 –manifold has several natural framed link descriptions, and we give an efficient method (via “grapes”) for showing that they are indeed the same 4–manifold. This leads to explicit handle pictures for the perturbation of singular fibers in an elliptic surface to a collection of fishtails. In the same vein, we show how the degeneration of a regular fiber to a singular fiber in an elliptic surface provides rich examples of Gromov’s compactness theorem.

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 کاملDual Decompositions of 4-manifolds Ii: Linear Invariants
This paper continues the study of decompositions of a smooth 4-manifold into two handlebodies with handles of index ≤ 2. Part I (Trans. Amer. Math. Soc. 354 (2002), 1373–1392) gave existence results in terms of spines and chain complexes over the fundamental group of the ambient manifold. Here we assume that one side of a decomposition has larger fundamental group, and use this to define algebr...
متن کاملBig Handlebody Distance Implies Finite Mapping Class Group
We show that if M is a closed three manifold with a Heegaard splitting with sufficiently big handlebody distance then the subgroup of the mapping class group of the Heegaard surface, which extend to both handlebodies is finite. As a corollary, this implies that under the same hypothesis, the mapping class group of M is finite.
