Abstract mathematics MT2116

This course is an introduction to formal mathematical reasoning, in which proof is central.

It introduces fundamental concepts and constructions of mathematics and looks at how to formulate mathematical statements in precise terms. It then shows how such statements they can be proved or disproved. It provides students with the skills required for more advanced courses in mathematics.
