Hyperbolicity VS Randomness in Cosmological Problems
Abstract
We discuss the hyperbolicity in perturbed Friedmann-Robertson-Walker Universe and the cummulative role of inhomogeneities and their link to observations. The degree of the randomness defined by the Kolmogorov stochasticity parameter, acts as an efficient descriptor for astrophysical datasets such as those of the cosmic microwave background radiation and X-ray clusters of galaxies.
