It is now well established that low-mass stars form from the collapse of dense cores within molecular clouds, and much of our knowledge of star formation has come from studies of relatively isolated dense cores. Yet isolated star formation is at best a simpler picture of the more relevant problem, how do stars form in clusters of 100 or more members, in a region extended over 1 pc, in a time period of 1 Myr, with a mass distribution following the initial mass function.
With the Submillimeter Array and single-dish mm/submm telescopes we are undertaking high spectral and spatial resolution molecular line observations of dense starless cores within nearby cluster forming regions, with the goal of comparing the properties of cores in cluster-forming regions to those of isolated dense cores, and so address the fundamental question, What are the initial conditions for star formation in clusters? In this contribution we will present our latest results for three regions.
