Strong existence and uniqueness for stable stochastic differential equations with distributional drift

Probability 2018-01-11 v1

Abstract

We consider the stochastic differential equation dXt=b(Xt)dt+dLt, dX_t = b(X_t) dt + dL_t, where the drift bb is a generalized function and LL is a symmetric one dimensional α\alpha-stable L\'evy processes, α(1,2)\alpha \in (1, 2). We define the notion of solution to this equation and establish strong existence and uniqueness whenever bb belongs to the Besov--H\"{o}lder space Cβ\mathcal{C}^\beta for β>1/2α/2\beta >1/2-\alpha/2.
