A key feature of packages such as Auto [12, 15], Content [24] and Matcont [11] is a collocation solver for two-point boundary value problems (BVPs); see also Chaps. 1 and 2. In conjunction with pseudo-arclength continuation, it is possible to find the solution of a two-point BVP and then continue it in parameters. This basic idea will be known to most readers as the standard technique to compute a one-parameter branch of periodic orbits. However, the continuation of BVPs is a much more versatile tool and the solution need not be a periodic orbit, but may be any specified orbit segment. For example, the continuation of a suitable orbit segment is utilized in the HomCont extension for the computation of connecting orbits; see [7] and also [13, 21, 43].

In this chapter we focus on the idea of representing an invariant global manifold of a dynamical system as a family of orbit segments, which can then be computed as a solution family of a suitable BVP. Note that the thus computed object lies entirely in the phase space, rather than the product of phase space and parameter space.
