Learning Outcomes

On successful completion of this module students should be able to:

1. Calculate the curvature and torsion of a space curve, demonstrate and use them to determine the shape of the curve.

2. Give definitions of the various different types of curvature associated to a surface and show how to compute them.

3. Demonstrate the first and second fundamental forms of a surface, how to compute them, and how they suffice to determine the local shape of the surface.

4. Appreciate the distinction between intrinsic and extrinsic aspects of surface geometry.

Brief description

Differential geometry is a branch of mathematics that uses calculus to study the geometric properties of curves and surfaces. Differential geometry provides the mathematical framework of many advanced theories in physics ranging from general relativity to soft matter (e.g. polymers, colloids and liquid crystals).

This module provides an introduction to differential geometry of curves and surfaces from both its local and global aspects. The presentation of the material will emphasize basic geometrical facts and requires a background in vector calculus.

Content

Review of basic concepts (vector calculus, linear transformations, Green’s theorem).

Local theory of curves – (Arc Length, The Frenet-Serret Apparatus).

Global Theory of Curves.

Local theory of surfaces (area element, minimal surfaces, mean and Gaussian curvature, the first and second fundamental forms).

Global theory of surfaces (The Gauss-Bonnet theorem).

Computer assisted problem classes (4 practical sessions) to help students answer questions in the problem sheets.
