Torus Knots and Links, Twist Neutrality and Biological Applications

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