  The shape of the stellar initial mass function (IMF) is one of the main uncertainties in our understanding of star formation, i.e., the conversion of gas into stars over cosmic time. It is usually assumed that the IMF in external galaxies is the same as in the disk of the Milky Way, where most studies of resolved stellar populations showed the IMF to be “universal”. However, the "universality" of the stellar IMF has recently been challenged: kinematics from integral-field spectroscopy of nearby galaxies as well as line strength studies of molecular features in spectra of early-type galaxies have shown evidence for a steepening of the low-mass IMF with increasing galaxy velocity dispersion. Deep star count studies in nearby dwarf galaxies seem to corroborate these findings. However, alternative explanations for the spectroscopic evidence have also started to appear in the literature. A non-universal IMF, if confirmed, would have important implications regarding our understanding of galaxy evolution. The main purpose of this workshop is to have a critical look at current and new evidence for variations of the IMF at sub-solar stellar masses. Recent observational and theoretical insights will be presented to evaluate whether and how the IMF may vary across different environments. Emphasis will be given to the role of future observing facilities in constraining the theoretical scenarios.
