Abstract

We study an analogue of Serre fibrations in the setting of $C^*$-algebra bundles. We derive in this framework a Leray–Serre type spectral sequence. We investigate a class of examples which generalise on one hand principal bundles with a $n$-torus as structural group and on the other hand non-commutative tori.
