Schauder estimates for stochastic transport-diffusion equations with L\'{e}vy processes

We consider a transport-diffusion equation with L'{e}vy noises and H"{o}lder continuous coefficients. By using the heat kernel estimates, we derive the Schauder estimates for the mild solutions. Moreover, when the transport term vanishes and $p=2$, we show that the H"{o}lder index in space variable is optimal.
