In the mathematics mathematical field of knot theory , a knot polynomial is a knot invariant in the form of a polynomial whose coefficients encode some of the properties of a given knot mathematics knot . History The first knot polynomial, the Alexander polynomial , was introduced by J. W. Alexander in 1923, but other knot polynomials were not found until almost 60 years later. In the 1960s, John Horton Conway John Conway came up with a skein relation for a version of the Alexander polynomial, usually referred to as the Alexander&ndash Conway polynomial . The significance of this skein relation was not realized until the early 1980s, when Vaughan Jones discovered the Jones polynomial . This led to the discovery of more knot polynomials, such as the so called HOMFLY polynomial . Soon after Jones discovery, Louis Kauffman noticed the Jones polynomial could be computed by means of a state sum model , which involved the bracket polynomial , an invariant of framing knot framed knots. This opened up avenues of research linking knot theory and statistical mechanics . In the late 1980s, two related breakthroughs were made. Edward Witten demonstrated that the Jones polynomial, and similar Jones type invariants, had an interpretation in Chern&ndash Simons theory . Victor Anatolyevich Vasilyev Viktor Vassiliev and Mikhail Goussarov started the theory of finite type invariant s of knots. The coefficients of the previously named polynomials are known to be of finite type after perhaps a suitable change of variables . In recent years, the Alexander polynomial has been shown to be related to Floer homology . The graded Euler characteristic of the Heegaard Floer homology knot Floer homology of Ozsv th and Szab is the Alexander polynomial.

In algebra, a multilinear polynomial is a polynomial that is linear in each of its variables. In other words, no variable occurs to a power of 2 or higher or alternatively, each monomial is a constant times a product of distinct variables. They are important in the study of polynomial identity testing , because if a multilinear polynomial is zero on a set of vectors that Linear span span the space, it will be zero everywhere. The Degree of a polynomial degree of a multilinear polynomial is the maximum number of distinct variables occurring in any monomial. ref A. Giambruno, Mikhail Zaicev.

The ring of radical polynomials is a graded algebra graded subalgebra of the ring of all polynomials.

In the mathematics mathematical field of knot theory , the bracket polynomial also known as the Kauffman bracket is a polynomial invariant of framed link s. Although it is not an invariant of knots or links as it is not invariant under type I Reidemeister move s , a suitably normalized version yields the famous knot invariant called the Jones polynomial . The bracket polynomial plays an important role in unifying the Jones polynomial with other quantum invariant s. In particular, Kauffman s interpretation of the Jones polynomial allows generalization to invariants of 3 manifold s. The bracket polynomial was discovered by Louis Kauffman in 1987. Definition The bracket polynomial of any unoriented link diagram L , denoted L , is characterized by the three rules O 1, where O is the standard diagram of the unknot Image kauffman bracket2.png 275px math langle O cup L rangle A 2 A 2 langle L rangle math The pictures in the second rule represent brackets of the link diagrams which differ inside a disc as shown but are identical outside.

Kauffman showed that L exists and is a regular isotopy invariant of unoriented links. It follows easily that F is an ambient isotopy invariant of oriented links. The Jones polynomial is a special case of the Kauffman polynomial, as the L polynomial specializes to the bracket polynomial .

In mathematics , in abstract algebra , a multivariate polynomial over a field whose Laplacian is zero is termed a harmonic polynomial . The harmonic polynomials form a vector space vector subspace of the vector space of polynomials over the field. In fact, they form a graded algebra graded subspace . The Laplacian is the sum of second partials with respect to all the variables, and is an invariant mathematics invariant differential operator under the action of the orthogonal group viz the Group mathematics group of rotations. The standard separation of variables theorem states that every multivariate polynomial over a field can be decomposed as a finite sum of products of a radical polynomial and a harmonic polynomial.
