abstract = {For time‐dependent partial differential equations,
parallel‐in‐time integration using the “parallel full
approximation scheme in space and time” (PFASST) is a
promising way to accelerate existing space‐parallel
approaches beyond their scaling limits. Inspired by the
classical Parareal method and multigrid ideas, PFASST allows
to integrate multiple time steps simultaneously using a
space–time hierarchy of spectral deferred correction
sweeps. While many use cases and benchmarks exist, a solid
and reliable mathematical foundation is still missing. Very
recently, however, PFASST for linear problems has been
identified as a multigrid method. In this paper, we will use
this multigrid formulation and, in particular, PFASST's
iteration matrix to show that, in the nonstiff and stiff
limit, PFASST indeed is a convergent iterative method. We
will provide upper bounds for the spectral radius of the
iteration matrix and investigate how PFASST performs for
increasing numbers of parallel time steps. Finally, we will
demonstrate that the results obtained here indeed relate to
actual PFASST runs.},
