Surfaces are a special class of topological spaces that crop up in many places in the world of mathematics. In this free course, you will learn to classify surfaces and will be introduced to such concepts as homeomorphism, orientability, the Euler characteristic and the classification theorem of compact surfaces.
Course learning outcomes
After studying this course, you should be able to:
explain the terms surface, surface in space, disc-like neighbourhood and half-disc-like neighbourhood
explain the terms n-fold torus, torus with n holes, Möbius band and Klein bottle
explain what is meant by the boundary of a surface, and determine the boundary number of a given surface with boundary
construct certain compact surfaces from a polygon by identifying edges
explain how a surface in space can be regarded as a topological space.
