Strong solutions for stochastic differential equations with jumps
General stochastic equations with jumps are studied. We provide criteria for
the uniqueness and existence of strong solutions under non-Lipschitz conditions
of Yamada-Watanabe type. The results are applied to stochastic equations driven
by spectrally positive L\'evy processes.Comment: 16 page
Multifractal analysis of superprocesses with stable branching in dimension one
We show that density functions of a -superprocesses are
almost sure multifractal for , and calculate
the corresponding spectrum of singularities.Comment: Published at http://dx.doi.org/10.1214/14-AOP951 in the Annals of
