I am aware that knots are characterized by polynomial invariants (Alexander , Jones, HOMFLY etc) but except for the Alexander polynomial, the other polynomials seem non-intuitive. In this context, could an arbitrary knot be represented as a sum of lissajous / fourier knots ( as in fourier series) ?? The difference between the former and the usual methods of knot decomposition would be the difference between representation as a sum of orthogonal knots and as a product of (prime / irreducible ??) knots . Would the invariant polynomials be the sum of the corresponding polynomials of the constituents ??
