Title: Primordial black hole dark matter from inflation

||
Abstract:
||

I will discuss the idea that the dark matter of the universe may be composed of black holes of primordial origin. I will mostly focus on light black holes (of mass several orders of magnitude smaller than that of the Sun) whose formation could have been triggered in the early universe by the dynamics of curvature fluctuations during inflation. In this context, I will specifically consider single-field inflation. If time allows, I will also comment on heavier black holes, in the range in which mergers are now being routinely observed by the LIGO/Virgo collaboration.
