Transversely Non Simple Knots

By proving a connected sum formula for the Legendrian invariant λ+ in knot Floer homology we exhibit infinitely many transversely non simple knots. Moreover we construct knots admitting many non-isotopic transverse representatives with equal selflinking number.

Ropelength, Connect Sum, and Cabling of Paired Knots

We define a class of knots called paired knots and show that for any paired conformation, K, with diagram, D, R(K) ≥ 4br(D). We then show that the connect sum of two paired knots is paired and that we can cable a paired knot such that the resulting (p, q)-cable knot is paired.

On the Edge-Difference and Edge-Sum Chromatic Sum of the Simple Graphs

‎For a coloring $c$ of a graph $G$‎, ‎the edge-difference coloring sum and edge-sum coloring sum with respect to the coloring $c$ are respectively‎ ‎$sum_c D(G)=sum |c(a)-c(b)|$ and $sum_s S(G)=sum (c(a)+c(b))$‎, ‎where the summations are taken over all edges $abin E(G)$‎. ‎The edge-difference chromatic sum‎, ‎denoted by $sum D(G)$‎, ‎and the edge-sum chromatic sum‎, ‎denoted by $sum S(G)$‎, ‎a...

Studying Uniform Thickness Ii: Transversally Non-simple Iterated Torus Knots

We prove that an iterated torus knot type fails the uniform thickness property (UTP) if and only if all of its iterations are positive cablings, which is precisely when an iterated torus knot type supports the standard contact structure. We also show that all iterated torus knots that fail the UTP support cabling knot types that are transversally non-simple.

An exact sum rule for transversely polarized DIS

The Operator Product Expansion provides expressions for the nth moments of g1(x) and g2(x) in terms of hadronic matrix elements of local operators for n = odd integer. In some cases these matrix elements are expected to be small leading to approximate sum rules for the odd moments of g1,2(x). We have shown how, working in a field-theoretic framework, one can derive expressions for the even mome...
