Based on a Special Session at the AMS Sectional Meeting in Las Vegas (NV) in April 2001, this volume discusses critical questions and new ideas in the areas of knotting and folding of curves in surfaces in three-dimensional space and applications of

In this thesis, we study the mechanics of tight physical knots. Knots are omnipresent in surgery, climbing, and sailing, with disastrous consequences when the filament or the rope fails to perform its function. Even if the importance of mechanical an

In the last few hundred years, mathematicians have been attempting to describe the topological and algebraic properties of mathematical knots. Regarding the study of knots, there exists a disconnect between examining a knot’s mathematical and physi

This manuscript provides a pedagogical introduction on how to determine and visualize simple physical knots occurring in polymers, proteins and DNA. We explain how the Alexander polynomial is computed and implemented in a simulation code, and how the

Numerical computations explored for this paper show that an upper bound on the ropelength of large knots with crossing number n grows as fast as nln2n. The algorithms to randomly generate samples of such large knots and to determine an upper bound on

Long biopolymers have a large probability of being knotted. These form of self-entanglement can arise spontaneously both in the context of nucleic acids and proteins [1]. Here we focus on the impact of such knots during the translocation through narr
