Completely Tubing Compressible Tangles and Standard Graphs in Genus One 3-manifolds
Ying-Qing Wu Abstra t. We prove a conjecture of Menasco and Zhang that if a tangle is completely tubing compressible then it consists of at most two families of parallel strands. This is related to problems of graphs in 3-manifold. A 1-vertex graph Γ in a 3manifold M with a genus 1 Heegaard splitting is standard if it consists of one or two parallel sets of core curves lying in the Heegaard spl...
متن کاملKnots, Links and Tangles
We start with some terminology from differential topology [1]. Let be a circle and ≥ 2 be an integer. An immersion : → R is a smooth function whose derivative never vanishes. An embedding : → R is an immersion that is oneto-one. It follows that () is a manifold but () need not be ( is only locally one-to-one, so consider the map that twists into a figure eight). A knot is a s...
متن کاملOn Tangles and Matroids
Given matroids M and N there are two operations M ⊕2 N and M ⊗ N. When M and N are the cycle matroids of planar graphs these operations have interesting interpretations on the corresponding link diagrams. In fact, given a planar graph there are two well-established methods of generating an alternating link diagram, and in each case the Tutte polynomial of the graph is related to polynomial inva...
متن کاملTangled Tangles
The Tangle toy [Zaw15, Zaw85] is a topological manipulation toy that can be twisted and turned in a variety of different ways, producing different geometric configurations. Some of these configurations lie in 3D space while others may be flattened into planar shapes. The toy consists of several curved, quarter-circle pieces fit together at rotational/twist joints. Each quarter-circle piece can ...
متن کاملHard Unknots and Collapsing Tangles
Classical knot theory is about the classification, up to isotopy, of embedded closed curves in three-dimensional space. Two closed curves embedded in three-dimensional space are said to be isotopic if there is a continuous family of embeddings starting with one curve and ending with the other curve. This definition of isotopy captures our intuitive notion of moving a length of elastic rope abou...
