| 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 of the It\^{o}--Tanaka trick. As applications, we establish an $L^2$-transportation cost inequality for these stochastic differential equations first, and then establish the unique strong solvability for a class of stochastic transport equations. |
