The Sheth–Tormen approximation is a theoretical framework used in cosmology, specifically in the context of understanding the mass function of dark matter halos in the universe. It was developed by R. K. Sheth and G. Tormen in 1999 and provides a way to model the number density of dark matter halos as a function of mass.
