Possibility of a cold cosmological singularity in the spectrum of primordial black holes
Abstract
Entropy generation accompanying evaporation of primordial black holes is considered. Bounds are obtained on the number of black holes with mass M less than 10 to the 13th g. It is shown that the initial cold matter, when transformed halfway into black holes with M of about 10 to the 4th g, acquires the presently observable entropy after the black-hole evaporation.
