Differential Geometry and Parametrization of 3D Knots

28 June 2011 - 29 June 2011

This event is part of an intensive research period:
Knots and Applications.


There has been much progress understanding the geometry of "physical" knots in the two decades since Lou Kauffman poetically described the essence of this topic:

“Unlike the classical machine that is composed of well-defined parts that interact according to well-understood rules (gears and cogs), the sliding interaction of two ropes under tension is extraordinary and interactive, with tension, topology, and the system providing the form which finally results.” (Knots and Physics, 1992).

Not only do ropes serve as the basic physical inspiration for natural geometric problems for knots and links, but so do bands, ribbons, fluids and other elastic or electromagnetic materials. This workshop will explore the recent progress in and prospects for this field.

This event is part of the 3-month intensive research period program on “Knots and Applications”, that takes place at the Centro di Ricerca Matematica "Ennio De Giorgi" of the Scuola Normale Superiore di Pisa, Italy, and that is organised in collaboration with INdAM.
