Seifert circles and knot polynomials
نویسنده
چکیده
In this paper I shall show how certain bounds on the possible diagrams presenting a given oriented knot or link K can be found from its two-variable polynomial PK defined in [3]. The inequalities regarding exponent sum and braid index of possible representations of K by a closed braid which are proved in [5] and [2] follow as a special case. Notation. In a diagram D for an oriented knot, write c(D) and c~(D) for the number

On Heegaard Floer Homology and Seifert Fibered Surgeries
We explore certain restrictions on knots in the three-sphere which admit non-trivial Seifert fibered surgeries. These restrictions stem from the Heegaard Floer homology (defined in [8]) for Seifert fibered spaces (compare [11]), and hence they have consequences for both the Alexander polynomial of such knots, and also their “knot Floer homology” (introduced in [10]). In particular, it is shown ...
متن کاملEXAMPLES IN CONCORDANCE 3 Seifert
In this paper we present a series of examples of new phenomena in the classical knot concordance group. First we show that for (almost) every Seifert form there is an infinite family of knots, distinct in concordance, having that form. Next we demonstrate that a number of results that are known to hold in higher dimensional concordance fail in the classical case. These include: (1) examples of ...

متن کاملTwisted Alexander Polynomials and Representation Shifts
For any knot, the following are equivalent. (1) The infinite cyclic cover has uncountably many finite covers; (2) there exists a finite-image representation of the knot group for which the twisted Alexander polynomial vanishes; (3) the knot group admits a finite-image representation such that the image of the fundamental group of an incompressible Seifert surface is a proper subgroup of the ima...
متن کاملKnot Signature Functions Are Independent
A Seifert matrix is a square integral matrix V satisfying det(V − V T ) = ±1. To such a matrix and unit complex number ω there is a signature, σω(V ) = sign((1 − ω)V + (1 − ω̄)V T ). Let S denote the set of unit complex numbers with positive imaginary part. We show {σω}ω∈S is linearly independent, viewed as a set of functions on the set of all Seifert matrices. If V is metabolic, then σω(V ) = 0...
