Symmetric equilibria of a thin elastic rod with self-contacts.
The thin elastic rod is a conventional model for the mesoscale structure of DNA. The symmetric multi-leafed closed equilibria with one multiple self-contact point are examined. The contact force is assumed to be pointwise and frictionless. The bifurcation diagram is presented for first branches of two- and three-leafed families including trefoil knots.
