摘要：

We show that spontaneous breaking of discrete or continuous symmetries does not necessarily imply either symmetry restoration or the thermal production of defects at high temperature (at least up to T∼MPlanck). This may imply that there is no domain wall problem. As an example we show how this applies to the Peccei-Quinn scenario. © 1995 The American Physical Society.
