JSJ decompositions of finitely generated groups are a fundamental tool in geometric group theory, encoding all splittings of a group over a given class of subgroups. The authors give a unified account of this theory with complete proofs and many examples. They introduce a simple and general definition of JSJ decompositions, the natural object being a deformation space of actions on trees, similar to outer space. In many cases of interest, this deformation space contains a canonical JSJ tree, which is invariant under automorphisms.
