Dynamical evolution of multiple populations in globular clusters

Spectroscopic and photometric studies have shown that many globular clusters host multiple stellar populations. Here we discuss some of the results of our investigations aimed at exploring the dynamical evolution of the structural properties of multiple-population clusters, the evolution of binary stars in multiple-populations clusters and the implications of the formation and dynamical evolution models of multiple-population clusters for the contribution of globular clusters to the assembly of the Galactic halo.
