Abstract:
Great attention has recently been paid to primordial black holes in the context of cosmology and gravitational-wave physics. After briefly reviewing primordial black holes, I will talk our recent work on primordial black hole formation in the matter-dominated era, which had been almost neglected until recently but turns out to be very important. I will discuss the production rate and the spin distribution of the primordial black holes.
