Description
Primordial black holes are a candidate for dark matter. Their seeds may be generated during inflation. I discuss the mechanism, why stochastic effects are expected to be important, and how they can be modelled consistently. I will also discuss new results on how stochastic fluctuations make the density profiles that collapse into black holes very choppy, unlike assumed so far.
