AULA GRASSANO

I will start by reviewing the physics of KK bubbles and their higher-dimensional generalizations. Secondly, I will move to discussing slightly more general situations where the shrinking modulus is the string coupling. Subsequently I will focus on cases where a Freund-Rubin flux is present, thus leading to the necessity of introducing a source. Finally, I will discuss the case of massive IIA on a 6-sphere as an explicit realization of the aforementioned mechanism and provide an appropriate physical interpretation.
