|
| Learning Outcomes: |
By the end of this unit, you will be able to:
- Demonstrate knowledge and understanding of the basic properties of projective spaces over arbitrary fields.
- Work with projective transformations.
- Demonstrate knowledge and understanding of the geometry of dual spaces, and of quadrics, especially conics.
- Simultaneously diagonalise conics, and identify when this is possible.
|
| Synopsis: | This course will use linear algebra to introduce you to projective geometry, the geometry of perspective. You will strengthen your understanding of linear algebra by exploring its geometrical significance. You will learn about important concepts of projective geometry such as projective linear subspaces, quadrics and cross-ratios and their relationships with both linear algebra and more familiar affine geometry.
|
| Content: | Projective spaces over arbitrary fields: projective subspaces, homogeneous and inhomogeneous coordinates, joins and intersections with dimension formula and applications.
Projective maps and transformations, points in general position, Desargues' Theorem.
Projective lines and cross ratios.
Dual projective spaces, annihilators and duality, relation with joins and intersections.
Quadrics: bilinear forms and quadratic forms, singular and non-singular quadrics, quadrics on a line, classification of conics, quadric surfaces, polars.
Pencils of quadrics, simultaneous diagonalizability and singular quadrics, simultaneous diagonalization for conics.
