SFH is invariant under Hamiltonian isotopy of the symplectomorphism. An isotopy is a homotopy for which each of the three maps is a bijection. For example, a path between two smooth embeddings is a smooth isotopy. Kauffman showed that "L" exists and is a regular isotopy invariant of unoriented links. Since each Reidemeister move can be made without affecting tricolorability, tricolorability is an isotopy invariant. The natural notion of equivalence is isotopy. Two quasigroups are isotopic if there is an isotopy between them. This result is an isotopy version of the weak Whitney embedding theorem. This result is an isotopy version of the strong Whitney embedding theorem. The oriented ambient isotopy classes of these four oriented knots are all distinct. Two knots are defined to be equivalent if there is an ambient isotopy between them. A phonetic isotopy is the recurrence of phonomenes, like in rhyme, assonance and alliteration. A prosodic isotopy is the recurrence of the same rhythm. This corresponds to the definition of isotopy. Let formula 5 and formula 6 be loops and let formula 7 be an isotopy.
