Module summary

Differential geometry has played a central and influential role in the development of 20th century pure mathematics and is fundamental to our understanding of the natural world. It is a key element of modern theories of particle physics and cosmology, and a crucial ingredient of all advanced approaches to mechanics and dynamical systems theory.This course offers an introduction to the subject by examining the geometry of curves and surfaces embedded in Euclidean space. The approach is to use familiar ideas from multivariable calculus and linear algebra to construct and study geometric objects, with elegant abstract definitions being illustrated by many concrete examples.

Objectives

On completion of this module, students should be able to:
a) recognise a regularly parametrized curve and compute its arc length and curvature;
b) construct and manipulate the Frenet frame of a curve in R^3;
c) construct the tangent and normal spaces of a parametrized surface;
d) compute the shape operator of an oriented surface, and manipulate it to find the associated curvatures of the surface;
e) construct simple minimal surfaces, and surfaces of prescribed Gaussian curvature.

Syllabus

- Parametrized curves in Euclidean space, their arc length and curvature, evolutes and involutes, the Frenet formulas.
- Parametrized surfaces, their tangent and normal spaces.
- The shape operator on an oriented surface and associated curvatures.
- Minimal surfaces, surfaces of prescribed Gaussian curvature and surfaces of revolution in R^3.

The topics covered are:
1. Parametrized curves in R^n, reparametrization, arc length.
2. Curvature of curves in R^n, signed curvature of curves in R^2, evolutes and involutes of planar curves, the Frenet formulae for curves in R^3 .
3. Parametrized surfaces in R^3, and surfaces of revolution.
4. The tangent and normal spaces of a parametrized surface. Oriented surfaces. Directional derivatives.
5. The shape operator of an oriented surface: principal, Gauss and mean curvatures.
6. Minimal surfaces and surfaces of prescribed Gaussian curvature.
