Query: Dynamical random multiplicative cascade model in 1+1 dimensions   Geometrical random multiplicative cascade processes are often used to model
positive-valued multifractal fields such as for example the energy dissipation
field of fully developed turbulence. A dynamical generalisation of these models
is proposed, which describes the continuous and homogeneous stochastic
evolution of the field in one space and one time dimension. Two-point
correlation functions are calculated.
