## Example Sentences

The Jacobians also have torsion points, just like elliptic curves, which circle back on themselves under repeated internal addition.

“This simple observation — that torsion points on the elliptic curve are the same as finite orbit points for a certain dynamical system — is what we use in our paper over and over and over again,” said DeMarco.

The two elliptic curves and their torsion points could not be immediately compared because they do not necessarily overlap.

The torsion points are sprinkled on the surfaces of the elliptic curves, but the two curves might have very different shapes.

The new work focuses on the torsion points of those elliptic curves.

Coulomb was the maker of the first instrument for measuring a current, which was known as the torsion balance.

Penaud's machine, relying only on india rubber under torsion, flies for some fifty yards.

On the other hand, the law of torsion could hardly be quite so simple, at all events, to the second order of approximations.

Its free motion differs entirely from that given it by torsion or stress.

The old freighter swung a great circle, its torsion jets blasting desperately in an effort to keep it on an even keel.
