Topology, the branch of mathematics that makes posible a rigorous study of continuity and continuous distortion, is a core mathematical discipline that provides the foundation for much of advanced mathematics and is a fascinating subject in its own right.
Our course will focus on the essential elements of the subject: topological spaces and functions between them. We will begin our study with careful examination of metric spaces using familiar examples (the real line and the plane) as well as other, more complicated examples. In this setting, we will formalize what it means for two objects to be close together. We may intuitively know what it means for objects (numbers, n-tuples, or functions) to be close together, but within the context of metric spaces we can define a general notion of distance that works in many settings. This will lead us to see that much of analyis does not depend on the specific distance at all but rather depends on the sets that are open in the metric space.
In a natural way, we will see that a topological space is the appropriate setting for describing interior, closure, and boundary of a set as well as continuous functions and the topological properties of compactness and connectedness. We will study topological subspaces, product spaces, the separation axioms and homeomorphisms concluding with surprising and surprisingly beautiful theorems.
There are no specific prerequisites for the course; all the essential topics will be introduced in the course itself, and the course should be accessible to any student with a modest background in mathematics. Students will be expected to follow carefully reasoned arguments and active participation will be encouraged. Grades will be based on regularly assigned problem sets. Our text will be Introduction to Topology (third edition) by Bert Mendelson.
