On the hull numbers of torus links
Introduced in [1] by Jason Cantarella, Greg Kuperberg, Robert B. Kusner, and John M. Sullivan, the hull number is a complexity measure for links similar to the bridge number. By definition, it is the maximum integer n such that for any realization of the link there is a point c ∈ R such that any plane through c intersects the curves representing the link at least 2n times. Clearly, the hull num...
متن کاملConstraints on Exact Lagrangians in Cotangent Bundles of Manifolds Fibered over the Circle
We give topological obstructions to the existence of a closed exact Lagrangian submanifold L →֒ T M , where M is the total space of a fibration over the circle. For instance, we show that π1(L) cannot be the free product of two non-trivial groups and that the difference between the number of generators and the number of relations in a finite presentation of π1(L) is less than two. Mathematics su...
متن کاملTorus Bundles over a Torus
1. If a compact Lie group P acts on a completely regular topological space E then E is said to be a principal P-bundle if whenever the relation px — x holds for pÇzP, x£E it follows that p = e, the identity of P. The orbit space X = E/P is called the base space and the map tt: E—>X carrying y into its orbit P-y is called the projection. Suppose now that G is a Lie group, 77i a closed subgroup o...

15 صفحه اولThe Alexander Polynomial of a Torus Knot with Twists
This note gives an explicit calculation of the doubly infinite sequence ∆(p, q, 2m), m ∈ Z of Alexander polynomials of the (p, q) torus knot with m extra full twists on two adjacent strings, where p and q are both positive. The knots can be presented as the closure of the p-string braids (δp) σ 1 , where δp = σp−1σp−2 . . . σ2σ1, or equally of the q-string braids (δq) σ 1 . As an application we...
