Notes on tiled incompressible tori

Leonid Plachta (2012)

Open Mathematics

Let Θ denote the class of essential tori in a closed braid complement which admit a standard tiling in the sense of Birman and Menasco [Birman J.S., Menasco W.W., Special positions for essential tori in link complements, Topology, 1994, 33(3), 525–556]. Moreover, let R denote the class of thin tiled tori in the sense of Ng [Ng K.Y., Essential tori in link complements, J. Knot Theory Ramifications, 1998, 7(2), 205–216]. We define the subclass B ⊂ Θ of typical tiled tori and show that R ⊂ B. We also...

Numerical application of knot invariants and universality of random knotting

Tetsuo Deguchi, Kyoichi Tsurusaki (1998)

Banach Center Publications

We study universal properties of random knotting by making an extensive use of isotopy invariants of knots. We define knotting probability ( P K ( N ) ) by the probability of an N-noded random polygon being topologically equivalent to a given knot K. The question is the following: for a given model of random polygon how the knotting probability changes with respect to the number N of polygonal nodes? Through numerical simulation we see that the knotting probability can be expressed by a simple function of...
