Yamada Polynomial and associated link of -curves
Youngsik Huh
The discovery of polynomial invariants of knots and links, ignited by V. F. R. Jones, leads to the formulation of polynomial invariants of spatial graphs. The Yamada polynomial, on…
Linearly Free Graphs
Youngsik Huh, Jung Hoon Lee
In this paper we are interested in an intrinsic property of graphs which is derived from their embeddings into the Euclidean 3-space . An embedding of a graph into $\…
An upper bound on stick numbers of knots
Youngsik Huh, Seungsang Oh
In 1991, Negami found an upper bound on the stick number of a nontrivial knot in terms of the minimal crossing number of the knot which is . In…
Knots with small lattice stick numbers
Youngsik Huh, Seungsang Oh
The lattice stick number of a knot type is defined to be the minimal number of straight line segments required to construct a polygon presentation of the knot type in the cubic lat…
Stick numbers of -bridge knots and links
Youngsik Huh, Sungjong No, Seungsang Oh
Negami found an upper bound on the stick number of a nontrivial knot in terms of the minimal crossing number of the knot which is . Furthermore…
Minimum lattice length and ropelength of 2-bridge knots and links
Youngsik Huh, Kyungpyo Hong, Hyoungjun Kim +2
Knots are commonly found in molecular chains such as DNA and proteins, and they have been considered to be useful models for structural analysis of these molecules. One interested…
