projective space

英語（米国） (en-US) 英語（イギリス） (en-GB)

名詞

(geometry) A kind of geometrical space in which only relation(s) of incidence between points and lines matter; in such a space distances or angles do not matter and parallelism (as in an affine space) does not matter either.

日本語の意味

射影空間: 幾何学において、点と直線の包含関係や交差関係（インシデンス関係）のみが重要視される空間。ここでは、距離や角度は無視され、平行性（アフィン空間における概念）も考慮されない。

英語の意味

(geometry) A kind of geometrical space in which only relation(s) of incidence between points and lines matter; in such a space distances or angles do not matter and parallelism (as in an affine space) does not matter either.

In projective space, parallel lines are treated as if they meet at a point at infinity, which simplifies many classical arguments.

射影空間では、平行な直線が無限遠点で交わると見なされ、これは多くの古典的な議論を簡素化します。
