HST is playing a central role in all the aspects of the study of multiple-population GCs. Recent HST-based high-precision proper motion studies are now adding another fundamental ingredient to the observational study of the dynamical properties of GCs and shedding light on the differences between the kinematical properties of different stellar populations. We will carry out an extensive survey of N-body simulations to explore the evolution of the kinematical properties of multiple-population GCs and identify the detailed kinematical fingerprints of their possible formation and dynamical histories. Our investigation will address a number of fundamental questions concerning the effects of dynamical evolution on the kinematical properties of different stellar populations, the implications of the differences in the initial spatial distributions of different stellar populations for the evolution of their kinematical properties, the effects of the external Galactic tidal field for clusters on different orbits, and the dependence of the kinematical properties on the stellar masses. Our study will build the theoretical framework necessary to interpret and guide HST kinematic studies of multiple populations and provide the theoretical tools to leverage these studies to test the viability of different multiple-population formation scenarios. The proposing team has extensive experience in the study of globular clusters and their multiple stellar populations. Bellini has extensive experience in the observational study of multiple populations in globular clusters and, in particular, in studies based on HST high-precision astrometry and photometry. Varri and Vesperini have extensive experience in the theoretical and numerical study of the dynamical evolution of globular clusters, globular clusters' internal kinematics, formation and evolution of multiple stellar populations.
