We study the dynamical evolution of the M87 globular cluster system (GCS) with a number of numerical simulations. We explore a range of different initial conditions for the GCS mass function (GCMF), for the GCS spatial distribution, and for the GCS velocity distribution. Our simulations include the effects of two-body relaxation, dynamical friction, and mass loss due to stellar evolution. We first confirm that an initial power-law GCMF such as that observed in young cluster systems can be…
