Abstract

We consider a one-dimensional stochastic equation , , with respect to a symmetric stable process of index . It is shown that solving this equation is equivalent to solving of a 2-dimensional stochastic equation with respect to the semimartingale and corresponding matrix . In the case of we provide new sufficient conditions for the existence of solutions of both equations with measurable coefficients. The existence proofs are established using the method of Krylov-s estimates for processes satisfying the 2-dimensional equation. On another hand, the Krylov-s estimates are based on some analytical facts of independent interest that are also proved in the paper.
