WeierstrassCurve.Affine.Point

{R : Type r} → [CommRing R] → WeierstrassCurve.Affine R → Type r

A nonsingular point on a Weierstrass curve W in affine coordinates. This is either the unique point at infinity WeierstrassCurve.Affine.Point.zero or a nonsingular affine point WeierstrassCurve.Affine.Point.some (x, y) satisfying the Weierstrass equation of W.
