It was speculations about isotopy that directly gave rise to the building of a mass spectrometer capable of separating the isotopes of the chemical elements.

An ambient isotopy, studied in this context, is an isotopy of the larger space, considered in light of its action on the embedded submanifold.

By the classification each is diffeomorphic to the unit disk and taking into account the isotopy theorem they are glued together by a diffeomorphism of the boundary.

A semantic isotopy, the narrower and most common type of isotopy, the one of Greimas's original definition, is the recurrence of semes.

In other words, the theorem defines a "'symplectic sum "'operation whose result is a symplectic manifold, unique up to isotopy.

Thus a virtual knot can be considered an ambient isotopy class of embeddings of the circle into thickened surfaces with the equivalence given by ( de ) stabilization.

In the comic he's talking about flexible ropes, and the corresponding topological object is the homeomorphic image of a circle, up to ambient isotopy.

Moreover, " f " has changed the orientation of the interval and " g " has not, which is impossible under an isotopy.
