Abstract
Multiple stellar populations in globular clusters pose serious challenges to our understanding of the chemical evolution, star-formation mechanisms and nucleosynthesis. Despite a huge observational efiort, none of the available scenarios is able to satisfactorily explain the observed chemical and photometric patterns to date. Asymptotic giant branch (AGB) stars of various mass-ranges, depending on the observed chemical features, are among the proposed polluters of the intra-cluster medium from which second-generations of stars formed. I summarise the observed properties of the multiple stellar populations in globular clusters and where the AGB scenario is able to qualitatively meet - or not - The observational constraints.
