Am Freitag, den 03. MÃ¤rz 2017 hÃ¤lt Herr Prof. von der Mosel im GebÃ¤ude 03, Raum 214 einen Vortrag zum Thema:
"We investigate the elastic behavior of knotted loops of springy wire. To this end we minimize in given knot classes the classic bending energy Ê k2 together with a small multiple of a repulsive potential R in order to penalize selfintersection. Our main objective is to characterize elastic knots, i.e., all limit contigurations of energy minimizing knots of the total energy Ê k2 + Î¸Ê as Î¸ tends to zero. For that, it turns out quite useful to look at various proofs of the classic FarÃ½-Milnor theorem on the total curvature Ê k of knotted curves."
