Crosscap Numbers and the Jones Polynomial Efstratia Kalfagianni and Christine Ruey
نویسنده
چکیده
We give sharp two-sided linear bounds of the crosscap number (nonorientable genus) of alternating links in terms of their Jones polynomial. Our estimates are often exact and we use them to calculate the crosscap numbers for several infinite families of alternating links and for several alternating knots with up to twelve crossings. We also discuss generalizations of our results for classes of non-alternating links.

On the Degree of the Colored Jones Polynomial Efstratia Kalfagianni and Christine Ruey
We use the colored Jones link polynomials to extract an invariant that detects semi-adequate links and discuss some applications.
متن کاملun 2 00 7 DEHN FILLING , VOLUME , AND THE JONES POLYNOMIAL
Given a hyperbolic 3–manifold with torus boundary, we bound the change in volume under a Dehn filling where all slopes have length at least 2π. This result is applied to give explicit diagrammatic bounds on the volumes of many knots and links, as well as their Dehn fillings and branched covers. Finally, we use this result to bound the volumes of knots in terms of the coefficients of their Jones...
متن کاملThe Homfly Polynomial for Links in Rational Homology 3-spheres
We construct a polynomial invariant, for links in a large class of rational homology 3-spheres, which generalizes the 2-variable Jones polynomial (HOMFLY). As a consequence, we show that the dual of the HOMFLY skein module of a homotopy 3-sphere is isomorpic to that of the genuine 3-sphere .
متن کاملKnot Cabling and the Degree of the Colored Jones Polynomial Ii
We continue our study of the degree of the colored Jones polynomial under knot cabling started in [8]. Under certain hypothesis on this degree, we determine how the Jones slopes and the linear term behave under cabling. As an application we verify Garoufalidis’ Slope Conjecture and a conjecture of [8] for cables of a two-parameter family of closed 3-braids called 2-fusion knots. 2010 Mathematic...
متن کاملA Jones Slopes Characterization of Adequate Knots
We establish a characterization of adequate knots in terms of the degree of their colored Jones polynomial. We show that, assuming the Strong Slope conjecture, our characterization can be reformulated in terms of “Jones slopes” of knots and the essential surfaces that realize the slopes. For alternating knots the reformulated characterization follows by recent work of J. Greene and J. Howie. 20...
