| 41. | Of the complex projective spaces ( Thom, 1952 ).
|
| 42. | The result is orientable, while the real projective plane is not.
|
| 43. | Cartan reformulated the differential geometry of ( projective, or conformal connection.
|
| 44. | Photogrammetry uses methods from many disciplines, including optics and projective geometry.
|
| 45. | If the projective plane is transitively on the lines of the plane.
|
| 46. | Complex projective space has many applications in both mathematics and quantum physics.
|
| 47. | Most projective special linear groups of large rank are Hurwitz groups,.
|
| 48. | It is easy to see that this pregeometry is a projective geometry.
|
| 49. | There is a bijection between and in a projective plane.
|
| 50. | All known projective planes have orders that are prime powers.
