A gauge-field approach to 3- and 4-manifold invariants

Bogusław Broda (1997)

Banach Center Publications

Similarity:

An approach to construction of topological invariants of the Reshetikhin-Turaev-Witten type of 3- and 4-dimensional manifolds in the framework of SU(2) Chern-Simons gauge theory and its hidden (quantum) gauge symmetry is presented.

Knot theory with the Lorentz group

João Faria Martins (2005)

Fundamenta Mathematicae

Similarity:

We analyse perturbative expansions of the invariants defined from unitary representations of the Quantum Lorentz Group in two different ways, namely using the Kontsevich Integral and weight systems, and the R-matrix in the Quantum Lorentz Group defined by Buffenoir and Roche. The two formulations are proved to be equivalent; and they both yield ℂ[[h]]h-valued knot invariants related with the Melvin-Morton expansion of the Coloured Jones Polynomial.

Combinatorics and topology - François Jaeger's work in knot theory

Louis H. Kauffman (1999)

Annales de l'institut Fourier

Similarity:

François Jaeger found a number of beautiful connections between combinatorics and the topology of knots and links, culminating in an intricate relationship between link invariants and the Bose-Mesner algebra of an association scheme. This paper gives an introduction to this connection.
