This course is on the topology of function spaces. We begin with an introduction to General Topology, with emphasis on separation axioms and compactness. After that we will consider various topologies on sets of continuous functions: the pointwise, compact-open and uniform topologies. Our goal is to prove the Arzela-Ascoli theorems that characterize compactness in certain function spaces. We will end with a few applications: to differential equations and the Riemann mapping theorem.
