KL5004 - Complex Variables

The module will be delivered using a combination of lectures and problem classes. A set of lecture notes and essential readings will be provided to support your learning. Problem classes will complement each taught topic and these sessions will enable you to enhance your problem-solving skills and obtain direct guidance and feedback.

You will be assessed by a written mid-term assignment (30%) and a formal examination (70%) at the end of the module. The latter will cover all aspects of the module and will assess your problem-solving abilities based on the use of a wide spectrum of complex calculus techniques.

Informal feedback on your work will be given continuously during the module. You will also receive formal assignment feedback at the end of the first semester and examination feedback at the end of the module.

Lectures and problem-solving classes will be the main point of academic contact, providing you with a formal teaching environment for core learning. Outside formal scheduled teaching, you will be able to contact the module team (module tutor, year tutor, programme leader) either via email or the open-door policy operated throughout the programme. Further academic support will be provided through technology-enhanced resources via the e-learning portal. You will also have the opportunity to give your feedback formally through periodic staff-student committees and directly to the module tutor at the end of the lecture.

All modules at Northumbria include a range of reading materials that students are expected to engage with. Online reading lists (provided after enrolment) give you access to your reading material for your modules. The Library works in partnership with your module tutors to ensure you have access to the material that you need.

Calculus in the complex plane is one of the most fundamental branches of mathematics with a wide range of applications in mathematical modelling, physics and engineering. The module will enable you to formulate mathematical problems in the language of functions of a complex variable using a combination of lectures and seminars. Lectures will focus on providing you with a thorough presentation of the theory and analytical tools underlying complex numbers and functions. You will then build upon these concepts in practical sessions to acquire advanced problem-solving skills through a variety of research-informed questions that will deepen your understanding of fundamental notions as well as highlight significant applications. You will receive constructive feedback during lectures and problem solving sessions throughout the year. The assessment will consist in an application-oriented assignment and a final examination that are designed to put into light your newly developed skills and techniques. The concepts and practical abilities gained in this module will advance your fundamental knowledge of mathematics and enhance your postgraduate perspectives.
