The JSJ decomposition of an object in a class of a topological spaces or groups is a maximal canonical way of cutting it up into simpler pieces. These were introduced in the study of 3-manifolds and have since been applied in more general situations. In this talk we shall first look at some general definitions and results before specialising to the case of hyperbolic groups and the Bowditch JSJ decomposition.
