Abstract

The unique strong solvability as well as the gradient estimates for stochastic differential equations with irregular growing drifts in low regularity Lebesgue--H\"{o}lder spaces $L^q(0,T;{\mathcal C}^\alpha({\mathbb R}^d))$ with $\alpha\in(0,1)$ and $q\in (2/(1+\alpha),2$) is proved, by means o...
