Multidimensional Multifractal Random Measures
Rhodes, Rémi; Université Paris Dauphine - Vargas, Vincent; Université Paris Dauphine

Formato:	Peer-reviewed Article,
Enlaces:	We construct and study space homogeneous and isotropic random measures (MMRM) which generalize the so-called MRM measures constructed by previous authors. Our measures satisfy an exact scale invariance equation and are therefore natural models in dimension 3 for the dissipation…
