In recent years there has been a growing interest for "applicable" aspects of classical knot theory in 3D, motivated by the discovery of new concepts and techniques with a strong geometric flavor, both in pure and applied mathematics. This, in turn, has given new impetus to such disparate areas as geometric topology, singularity theory, geometric dynamics, topological fluid mechanics, topological quantum field theory, and others. Meanwhile, continuous progress in computational techniques and numerical simulation on the one hand, and applied sciences such as polymer physics, DNA biology, neural networks, etc., on the other, have benefited from these developments.
New results on the groundstate energy of physical knots and links, for example, show that local and global geometric aspects, topological classification and complexity issues, including framing, chirality, etc., are all important issues in the development of a topological field theory. There is therefore a call for more work towards a "geometric" knot theory, accompanied by advanced numerical modeling of tight/ideal knots and numerical simulations of structural complexity issues.
This intensive research period is devoted to explore analytical, numerical and applied aspects of geometric knot theory, with particular emphasis on the following topics: Theory: aspects of hyperbolic geometry, classification issues, differential geometric aspects of knots and links, analytical and parametric representation of knots, links and braids, tubular knots, invariants for applications, energy functionals, chirality issues, Seifert surfaces. Numerics: implementation of energy functionals, local/global minimum, tightening and ideal shapes, role of framing and chirality, twist and satellites. Applications: magnetic fields, elastic systems, energy quantization, quantum entanglement, DNA biology.
