# Unit information: Introduction to Geometry in 2018/19

Please note: you are viewing unit and programme information for a past academic year. Please see the current academic year for up to date information.

Unit name Introduction to Geometry MATH20004 20 I/5 Teaching Block 2 (weeks 13 - 24) Dr. Mackay Not open Calculus 1, Analysis 1A & Linear Algebra & Geometry 1 None School of Mathematics Faculty of Science

## Description

The aim of this unit is to introduce fundamental concepts in geometry in a hands-on and rigorous way, focused on curves and surfaces, and to lay the foundations for more advanced courses in later years.

Geometry is central to mathematics, both as a subject in its own right and as an essential viewpoint on nearly every area of pure and applied mathematics. This course focuses on the geometry of curves and surfaces in R2 and R3, continuing on from calculus.

A key concept is the curvature of a surface, which describes locally how it bends, whether it is flat like Euclidean space, positively curved like a sphere, or, less-familiarly, negatively curved like a saddle. A major goal is to prove the Gauss-Bonnet theorem, which links the curvature of a surface to its overall shape.

## Intended learning outcomes

By the end of the course the students should

• have developed an understanding of the basic notions and results in differential geometry, like local coordinates, tangents and normals, curvature and fundamental forms, Gauss-Bonnet.
• be able to apply the methods to the description and solution of problems from pure and applied mathematics.

## Teaching details

The course will be based on lectures, with weekly homework problems and a weekly problems class.

## Assessment Details

100% Examination

Raw scores on the examinations will be determined according to the marking scheme written on the examination paper. The marking scheme, indicating the maximum score per question, is a guide to the relative weighting of the questions. Raw scores are moderated as described in the Undergraduate Handbook.

If you fail this unit and are required to resit, reassessment is by a written examination in the August/September Resit and Supplementary exam period.
