Projective geometry and projective metrics
Herbert Busemann, Paul J. Kelly
Geometers value basic results as much as they do the methods of projective and non-Euclidean geometry. This book emphasizes that fact, taking a non-traditional approach. Topics include the projective plane, polarities and conic sections, affine geometry, projective metrics, and non-Euclidean and spatial geometry. Includes numerous figures. 1953 edition.
