Τhe importance of being open

Abstract: I will talk about some interesting features of open cosmologies (i.e. four-dimensional spacetimes of Friedmann-Lemaître-Robertson-Walker type with three-dimensional spatial slices that are hyperbolic) related to compactifications of ten-dimensional supergravity on certain classes of six-dimensional spaces.
