Supercoiled Tangles and Stick Numbers of 2-bridge Links

Geometric Topology 2013-08-06 v1

Abstract

Utilizing both twisting and writhing, we construct integral tangles with few sticks, leading to an efficient method for constructing polygonal 2-bridge links. Let L be a two bridge link with crossing number c, stick number s, and n tangles. It is shown that s is less than or equal to 2/3 c + 2n+3 . We also show that if c > 12n+3, then minimal stick representatives do not admit minimal crossing projections.
