The invariant of n-punctured ball tangles

Jae-Wook Chung

Based on the Kauffman bracket at $A = e^{iπ /4}$ , we defined an invariant for a special type of $n$ -punctured ball tangles. The invariant $F^{n}$ takes values in the set $PM_{2\times2^…

The Algebraic Structure of n-Punctured Ball Tangles

Jae-Wook Chung

We consider a class of topological objects in the 3-sphere $S^{3}$ which will be called $n$ -punctured ball tangles. Using the Kauffman bracket at $A = e^{iπ /4}$ , an invariant for a sp…

On n-punctured ball tangles

Jae-Wook Chung, Xiao-Song Lin

We consider a class of topological objects in the 3-sphere $S^{3}$ which will be called {\it $n$ -punctured ball tangles}. Using the Kauffman bracket at $A = e^{π i /4}$ , an invariant for…

On the bridge number of knot diagrams with minimal crossings

Jae-Wook Chung, Xiao-Song Lin

Given a diagram $D$ of a knot $K$ , we consider the number $c (D)$ of crossings and the number $b (D)$ of overpasses of $D$ . We show that, if $D$ is a diagram of a nontrivial knot $K$ …
