| 11. | This notion finds utility in projective geometry and complex analysis.
 
  | 
 | 12. | This early 19th century projective geometry was intermediate from analytic geometry to algebraic geometry.
 
  | 
 | 13. | A corollary to this theorem yields the complete structure of all finite projective geometry.
 
  | 
 | 14. | This approach leads to a theory of non-commutative projective geometry.
 
  | 
 | 15. | Projective geometry has in fact the simplest and most elegant synthetic expression of any geometry.
 
  | 
 | 16. | This type of relation appears frequently in projective geometry.
 
  | 
 | 17. | Juel did research on projective geometry, algebraic curves, polyhedra, and surfaces of revolution from ovals.
 
  | 
 | 18. | I'm not formally studying mathematics, but am trying to get my head round projective geometry.
 
  | 
 | 19. | He lectured on the philosophy of mathematics, and on mechanics, analytics and descriptive and projective geometry.
 
  | 
 | 20. | Indeed, in projective geometry a cylindrical surface is just a special case of a conical surface.
