In mathematics, a Cayley–Klein metric is a metric on the complement of a fixed quadric in a projective space which is defined using a cross-ratio. The construction originated with Arthur Cayley's essay "On the theory of distance" where he calls the quadric the absolute. The construction was developed in further detail by Felix Klein in papers in 1871 and 1873, and subsequent books and papers. The Cayley–Klein metrics are a unifying idea in geometry since the method is used to provide metrics in hyperbolic geometry, elliptic geometry, and Euclidean geometry. The field of non-Euclidean geometry rests largely on the footing provided by Cayley–Klein metrics.

  • En mathématiques, une métrique de Cayley-Klein est une métrique définie sur le complémentaire d'une quadrique fixée d'un espace projectif, la quadrique absolue, à l'aide du birapport. Cette métrique a été construite par Arthur Cayley en 1859 ; la construction fut complétée par Felix Klein entre 1871 et 1873. Les métriques de Cayley-Klein fournissent un cadre unifié aux différentes géométries euclidiennes et non euclidiennes, en y définissant la notion de distance par la même construction dans tous les cas.

  • The question recently arose in conversation whether a dissertation of 2 lines could deserve and get a Fellowship. ... Cayley's projective definition of length is a clear case if we may interpret "2 lines" with reasonable latitude. ... With Cayley the importance of the idea is obvious at first sight. (en)
