SUMMARY:Symmetric Criticality for Ropelength - Mastin\, M (University of G
 eorgia)

DESCRIPTION:The ropelength of a link embedded in $R^3$ is the ratio of the
  curve's length to its thickness. Jason Cantarella\, Joe Fu\, Rob Kusner\,
  and John Sullivan have developed a theory of first order criticality for 
 ropelength. We will discuss an extension of this work for the case of link
  conformations with rigid rotational symmetry. As an application we will p
 rove that there is an infinite class of knots for which there are geometri
 cally distinct ropelength critical conformations. This work is joint with 
 Jason Cantarella\, Jennifer Ellis\, and Joe Fu.\n\n
