چکیده

We consider Wilson loop observables for Chern-Simons theory at large N and its topological string dual and extend the previous checks for this duality to the case of links. We find an interesting structure involving representation/spin degeneracy of branes ending on branes which features in the large N dual description of Chern-Simons theory. This leads to a refinement of the integer invariants for links and knots. We illustrate our results with explicit computations on the Chern-Simons side.

Quasi-alternating Links and Odd Homology: Computations and Conjectures

We present computational results about quasi-alternating knots and links and odd homology obtained by looking at link families in the Conway notation. More precisely, we list quasi-alternating links up to 12 crossings and the first examples of quasi-alternating knots and links with at least two different minimal diagrams, where one is quasi-alternating and the other is not. We provide examples ...

On the Large N Limit, W ∞ Strings, Star Products, AdS/CFT duality Nonlinear Sigma Models on AdS Spaces and Chern-Simons p-Branes

It is shown that the large N limit of SU (N) YM in curved m-dim backgrounds can be subsumed by a higher m + n dimensional gravitational theory which can be identified to an m-dim generally invariant gauge theory of diffs N , where N is an n-dim internal space (Cho, Sho, Park, Yoon). Based on these findings, a very plausible geometrical interpretation of the AdS/CF T correspondence could be give...

Knots, Braids and BPS States in M-Theory

In previous work we consideredM -theory five branes wrapped on elliptic Calabi-Yau threefold near the smooth part of the discriminant curve. In this paper, we extend that work to compute the light states on the worldvolume of five-branes wrapped on fibers near certain singular loci of the discriminant. We regulate the singular behavior near these loci by deforming the discriminant curve and exp...

We show that several classes of links, including semiadequate links and Whitehead doubles of semiadequate knots, have non-trivial Jones polynomial. Then we prove that there are infinitely many positive knots with no positive minimal crossing diagrams, and infinitely many achiral knots of odd crossing number. Some applications to the twist number of a link, Mahler measure and the hyperbolic volu...

Surgery Descriptions and Volumes of Berge Knots I: Large Volume Berge Knots

By obtaining surgery descriptions of knots which lie on the genus one fiber of the trefoil or figure eight knot, we show that these include hyperbolic knots with arbitrarily large volume. These knots admit lens space surgeries and form two families of Berge knots. By way of tangle descriptions we also obtain surgery descriptions for these knots on minimally twisted chain links.
