Title: Coordinates change and random fields

Abstract:The time change of one parameter processes is a powerful tool well investigated so far. We present in this talk some theoretical aspects concerning the coordinates change of multiparameter processes and some applications to the analysis of the cosmic microwave background radiation. We consider fractional powers of positive definite operators such as the (time) fractional derivative or the fractional Laplacean.
