In this proceedings paper we discuss the dynamical complexity arising from the interplay between supersonic turbulence and self-gravity and introduce the process of gravoturbulent fragmentation (Σ). The fact that Galactic molecular clouds are highly filamentary can be explained by a combination of compressional flows and shear (Σ). The dynamical evolution of nascent star clusters is very complex. This strongly influences the stellar mass spectrum (Σ). The equation of state (EOS) plays a pivotal role in the fragmentation process. Under typical cloud conditions, massive stars form as part of dense clusters. However, for gas with effective polytropic index greater than unity star formation becomes biased towards isolated massive stars, which may be of relevance for understanding Pop III stars (Σ).
