Geometry | Department of Mathematics


Credits: 4 (3 lectures and 1 tutorial weekly)

Prerequisites: MAT 360 Linear Algebra II for undergraduates, MAT 660 Linear Algebra for graduate students

Overview: This course provides a bridge to modern geometry. It provides a unified axiomatic approach leading to a coherent overview of the classical geometries (affine, projective, hyperbolic, spherical), culminating in a treatment of surfaces that sets the stage for future study of differential geometry.

Detailed Syllabus:

  1. Affine geometry – finite planes, planes over fields, affine transformations, collineations, affine coordinates, triangles and parallelograms, classical theorems of Menelaus and others.
  2. Projective geometry – finite planes, projective completion of affine planes, homogeneous coordinates, projective transformations, collineations, projective line, poles and polars.
  3. Conics – affine and projective classifications, group actions.
  4. Euclidean geometry – isometries, triangles, parallelograms, length minimizing curves, geometry of plane curves.
  5. Hyperbolic geometry – Poincare upper half plane, Poincare metric, distance function, triangles and area, two-point homogeneity.
  6. Spherical geometry – Sphere, tangent space, great circles, triangles and area, two-point homogeneity
  7. Surfaces – Level surfaces, parametrized surfaces, curvature, Gauss theorem, introduction to manifolds.
