Summary
A cosmological scenario according to which our universe experienced space-time compactifications twice in its early development is investigated through toy models. In this scenario gauge configurations on an extra space play essential roles to bring about a change of the dimensionality of the compactified space. Simple models are offered and their behaviour at finite temperature is examined. A possibility of causing inflation and problems on our scenario is argued briefly.
Riassunto
Si ricerca per mezzo di modelli giocattolo uno scenario cosmologico secondo cui il nostro universo avrebbe subito compattificazioni dello spazio tempo per due volte durante il suo sviluppo primitivo. In questo scenario le configurazioni del gauge su uno spazio extra giocano ruoli essenziali nel causare un cambiamento della dimensionalità dello spazio reso compatto. Si offrono modelli semplici e si esamina il loro comportamento a temperatura finita. Si discute brevemente la possibilità di causare inflazione e problemi sullo scenario.
Резюме
Используя модели, исследуется космологический сценарий, в котором наша вселенная дважды испытывала компактификации пространства-времени в предыдушие эпохи. В этом сценарии калибровочные ковфитурации на дополнительном пространстве играют сушественныю роль в изменении размерности компактифицированного пространства. Предлагаются простые модели и исследуется их поведение при конечных температурах. Вкратце обсуждается возможность причинной инфляции и проблемы, с вязанные с нашим. сценарием.
