摘要：
We study the pointwise regularity properties of the L,vy fields introduced by T. Mori; these fields are the most natural generalization of L,vy processes to the multivariate setting. We determine their spectrum of singularities, and we show that their Holder singularity sets satisfy a large intersection property in the sense of K. Falconer.
