ON SYMMETRY CHANGES DURING PHASE TRANSITIONS IN THE EARLY HOT UNIVERSE AND CRYSTALLINE SOLIDS

The results of a comparative analysis of phase transitions that occur in the early hot Universe and various crystalline substances are presented. It is assumed that the principle of preserving macroscopic symmetry should take place in all types of phase transitions. It is shown that many cosmological and crystallographic problems can be solved on the basis of the principle of macroscopic conservation.
