Abstract
A multifractal-like representation for multi-time, multi-scale velocity cor relation in turbulence and dynamical turbulent models is proposed. The impo rtance of subleading contributions to time correlations is highlighted. The fulfillment of the dynamical constraints due to the equations of motion is thoroughly discussed. The predictions stemming from this representation ar e tested within the framework of shell models for turbulence. (C) 1999 Else vier Science B.V. All rights reserved.
