Topology

Topology is the natural evolution of analysis to a more general level. Whereas analysis was concerned with the implications of continuity on the familiar spaces of Rn and Cn, topology seeks to explore all the types of mathematical structures where analytical concepts can be applied in some form. From the loose structure of point-set topology to the requirement that objects admit some type of smooth structure in differential topology, this division studies the implications of applying analysis to all the types of objects where it makes sense to define some sort of analytical structure. Note that while topology originally evolved from the study of partial differential equations by Poincaré, the modern student need only bring a knowledge of limits and continuity from a good calculus course with them, as well as a basic understanding of what a group is.

Course Goal[edit]

The goal of this course is to introduce and build proficiency with the basic machinery of modern topology using examples from an area of topology that is well understood, such as the topology of surfaces. The student will then be well-prepared to encounter the strangeness and pitfalls of more abstract and higher-dimensional topology.

Recommended Reading[edit]

Like all other mathematics, topology can only be learned by doing it. While this site provides a supportive community of peers and teachers, you also need a well-organized and well-written text that you can study anywhere to learn from those actively participating in field.
