Jones polynomial 1984
In the mathematical field of knot theory, the Jones polynomial is a knot polynomial discovered by Vaughan Jones in 1984. Specifically, it is an invariant of an oriented knot or link which assigns to each oriented knot or link a Laurent polynomial in the variable [math]\displaystyle{ t^{1/2} }[/math] with integer coefficients.
