Graduate attributes:

This course provides a good understanding of basic topological properties,
constructions and reasoning in three dimensional space, classical curves and surfaces, and
understand the meaning of curvature for curves and surfaces, and appreciates the connections
between topology and differential geometry for surfaces.   On completion you will know how to compute the
fundamental group for a range of topological spaces and understand the importance of homotopy
relation.  You will know how to differentiate between two manifolds using algebraic
topology tools and differential geometry tools.  You will gain an appreciation for the importance
of quadrics to approximate surfaces at a point, and you will be able to make explicit
computations for a wide variety of examples, computing Frenet frames for curves, and first and
second fundamental forms for many surfaces. Algebraic surfaces and surfaces of revolution will
provide a good source of examples.  You will understand the idea of a developable surface and
its applications.
 
The above outcomes are related to Research, inquiry and analytical thinking abilities, communication,
and Information literacy.

Course Overview

Topology and differential geometry both deal with the study of shape: topology from a continuous and differential geometry from a differentiable viewpoint.

This course begins with an introduction to general topology. We then study curves in space and how they bend and twist, and the topology of curves. We then consider surfaces, studying the first and second fundamental forms introduced by Gauss, the various measures of curvature and what they mean for the external and internal appearance and properties of surfaces. We prove the important Gauss-Bonnet theorem and use it to examine topological properties of surfaces, such as the Euler Characteristic. We finish with a look at the hyperbolic plane and a look forward to general Riemannian geometry.
