Topological Aspects of the Birth of the Universe

摘要

It is noted that in Hartly-Hawking's approach to the calculation of the Universe birth amplitude there are topological restrictions on the properties of born Universe and matter fields in it. These restrictions are obtained in explicit form in particular cases. The possible consequence is the statement that the baryon charge of our Universe would be zero in the absence of the baryon number nonconserving interactions. 8 refs. (Atomindex citation 18:007509)
