Torus Knots and Links, Twist Neutrality and Biological Applications

Presented by: 
J Bohr [DTU]
Date: 
Thursday 6th December 2012 - 16:25 to 16:45
Venue: 
INI Seminar Room 1
Session Title: 
Quantized flux tubes and vortices
Session Chair: 
Robert Kerr
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].
