Dr Eleni Katirtzoglou

This course is compulsory on the BSc in Mathematics and Economics and BSc in Mathematics with Economics. This course is available on the BSc in Business Mathematics and Statistics, BSc in Econometrics and Mathematical Economics and BSc in Statistics with Finance. This course is available as an outside option to students on other programmes where regulations permit. This course is available with permission to General Course students.

Introduction to Abstract Mathematics (MA103), or some equivalent giving experience with formal proofs, convergence of sequences and continuity of functions. 

This is a course in real analysis for those who have already met the basic concepts of sequences and continuity on the real line. Here we generalize these concepts to Euclidean spaces and to more general normed spaces and metric spaces.  These more general spaces are introduced at the start and are emphasized throughout the course.

Topics covered are:

• Metric and normed spaces, open and closed sets, topological properties of sets and equivalent metrics.
• Sequences in metric spaces, compactness, completeness, pointwise and uniform convergence of sequences of functions.
• Infinite series on the real line and in normed spaces.
• Continuity of real valued functions and of functions between metric spaces, uniform continuity and Lipschitz condition.
• Differentiation of real valued functions, the mean value theorem, differentiation of functions between Euclidean spaces (Fréchet derivative) and partial derivatives.
• Riemann integral and the fundamental theorem of calculus.

22 hours of lectures and 10 hours of classes in the MT.

Written answers to set problems will be expected on a weekly basis.

A comprehensive pack of lecture notes will be provided.The following may prove useful:

• Robert G Bartle & Donald R Sherbert, Introduction to Real Analysis 
• W A Sutherland, Introduction to Metric and Topological Spaces
• Tom Apostol, Mathematical Analysis, second edition.
• Walter Rudin, Principles of Mathematical Analysis, third edition.

Exam (100%, duration: 2 hours) in the main exam period.
