释义 | non-Euclideanadj. Mathematics. Not Euclidean, not in accordance with the principles of Euclid. non-Euclidean geometry n. a system of geometry in which one or more of the axioms of Euclidean geometry is dispensed with, esp. the postulate that there is one and only one line through a given point parallel to a given line; also called metageometry. non-Euclidean space n. a space whose geometry is non-Euclidean.

Networks p. xvi Tensor analysis may be considered as an extension and generalization of vector analysis from three- to n-dimensional spaces and from Euclidean to non-Euclidean spaces. 1956 E. H. Hutten Lang. Mod. Physics iii. 113 In the beginning of the 19th century..Bolyai, Lobatchevsky, and (later) Riemann demonstrated that other axiom systems could be constructed representing various kinds of non-Euclidean geometry. 1972 M. Kline Math. Thought xxxvi. 872 From about 1813 on Gauss developed his new geometry which he first called anti-Euclidean geometry, then astral geometry, and finally non-Euclidean geometry. 1990 Q.
