Quantum Knots and Lattices, or a Blueprint for Quantum Systems
... Theorem 5.5. Two PL knots K1 and K2 are of the same knot type if and only if they have 1) The same inextensible knot type, i.e. K1 ≈ K2 , and 2) The same length, i.e., |K1 | = |K2 | . Thus, nothing from classical knot theory is lost with the above modified definition of knot type. But on the other h ...
