Torus Knots and Links, Twist Neutrality and Biological Applications

Bohr, J (DTU)
Thursday 06 December 2012, 16:25-16:45

Seminar Room 1, Newton Institute

Abstract

We present mathematical restrictions for torus knots and links, and for bent helices. The concept of twist neutrality is developed for bent and coiled structures and biological applications are reviewed [1,2].
