KnowraProjective spaceLinked fromLinked fromThe 16 pages that link to Projective space, each with the reason it gives.All 16Broader topic 5Related 8Narrower topic 3Coordinate systemRelated: Projective coordinates represent directions and points at infinity beyond ordinary affine coordinates.Equivalence relationRelated: Nonzero vectors define the same projective point when one is a nonzero scalar multiple of another.Elliptic curveRelated: Projective coordinates include points at infinity needed for the complete curve.Affine spaceRelated: Projective geometry forgets parallelism that affine spaces retain.Algebraic curveRelated: Projective space provides a setting where curves include their points at infinity.Rational pointRelated: Projective coordinates represent rational points up to nonzero scalar multiplication.Equivalence classRelated: Nonzero vectors on the same line are identified as one equivalence class.Corrado SegreRelated: Segre investigated configurations and varieties in projective spaces of several dimensions.
