Models of fluctuating(or random) geometries provide many challenging problems. One of them is the definition and interpretation of correlation functions. The usual formulation of the correlation function as a correlator of two observables in two fixed points at some distance apart is possible only if we have a fixed system of coordinates and a metric. This may be suitable for the perturbation t...

A bstract Asymptotic (late-time) cosmology depends on the asymptotic (infinite-distance) limits of scalar field space in string theory. Such feature an exponentially decaying potential V ~ exp(− cϕ ) with corresponding Hubble scale H $$ \sqrt{{\dot{\phi}}^2+2V} ϕ ̇</mm...
