<p>A surface (2-manifold) is of finite type if its fundamental group is finitely generated. The classification up to homeomorphism of finite-type surfaces is one of my favourite theorems in all of mathematics. Remarkably, there is a classification up to homeomorphism of infinite-type surfaces! This talk will be a survey on the classification of infinite-type surfaces and their mapping class groups. Time permitting I will talk about recent work involving something called the surviving arc graph.</p>
