Rather than being a number like the Euler characteristic . or a boolean invariant like orientability, the fundamental group associates a . to ., denoted .. Furthermore if . is homeomorphic to ., then the fundamental groups . and . are iso

In order to work them out, we will try to build them up from spaces whose fundamental groups we already know. Before we introduce the general theorem, let us look at an example, that of the wedge of two circles, meaning two circles tha

There are higher-dimensional versions of the fundamental group, known as homotopy groups and denoted by .; these are defined in terms of homotopy classes of maps from . to .. In computing ., we already found that we needed a somewhat involved argument. Nonet

Introduction to Group Theory, spaces are homeomorphic or not. However, there is a wide class of other invariants, which associate other sorts of objects to spaces. For the next few chapters, we will build up to the fundamental group, and then we will work on understanding its behavior.
