Query: Pulsational pair-instability supernovae: gravitational collapse,
  black-hole formation, and beyond   We investigate the final collapse of rotating and non-rotating pulsational
pair-instability supernova progenitors with zero-age-main-sequence masses of
60, 80, and 115$\mathrm{M}_\odot$ and iron cores between 2.37$\mathrm{M}_\odot$
and 2.72$\mathrm{M}_\odot$ by 2D hydrodynamics simulations. Using the general
relativistic NADA-FLD code with energy-dependent three-flavor neutrino
transport by flux-limited diffusion allows us to follow the evolution beyond
the moment when the transiently forming neutron star (NS) collapses to a black
hole (BH), which happens within 350$-$580 ms after bounce in all cases. Because
of high neutrino luminosities and mean energies, neutrino heating leads to
shock revival within $\lesssim$250 ms post bounce in all cases except the
rapidly rotating 60$\mathrm{M}_\odot$ model. In the latter case, centrifugal
effects support a 10% higher NS mass but reduce the radiated neutrino
luminosities and mean energies by $\sim$20% and $\sim$10%, respectively, and
the neutrino-heating rate by roughly a factor of two compared to the
non-rotating counterpart. After BH formation, the neutrino luminosities drop
steeply but continue on a 1$-$2 orders of magnitude lower level for several 100
ms because of aspherical accretion of neutrino and shock-heated matter, before
the ultimately spherical collapse of the outer progenitor shells suppresses the
neutrino emission to negligible values. In all shock-reviving models BH
accretion swallows the entire neutrino-heated matter and the explosion energies
decrease from maxima around 1.5$\times$10$^{51}$erg to zero within a few
seconds latest. Nevertheless, the shock or a sonic pulse moves outward and may
trigger mass loss, which we estimate by long-time simulations with the
PROMETHEUS code. We also provide gravitational-wave signals.
