= Knot polynomial
{wiki=Knot_polynomial}
A knot polynomial is a mathematical invariant associated with knots and links in the field of knot theory, which is a branch of topology. Knot polynomials are used to distinguish between different knots and to study their properties. Some of the most well-known knot polynomials include: 1. **Alexander Polynomial**: This is one of the earliest knot polynomials, defined for a knot or link as a polynomial in one variable. It provides insights into the topology of the knot and can help distinguish between different knots.
