We consider elliptic equations with operators $L=a^{ij}D_{ij}+b^{i}D_{i}-c$ with $a$ being almost in VMO, $b\in L_{d}$ and $c\in L_{q}$, $c\geq0$, $d>q\geq d/2$. We prove the solvability of $Lu=f\in L_{p}$ in bounded $C^{1,1}$-domains, $1 0$. Weak uniqueness of the martingale problem associated with such operators is also obtained.

具有 VMO a、b$\in L_d$ 和 c$\in L_{d/2}$ 的椭圆方程

我们考虑具有运算符 $L=a^{ij}D_{ij}+b^{i}D_{i}-c$ 的椭圆方程,其中 $a$ 几乎在 VMO 中,$b\in L_{d}$ 和$c\in L_{q}$, $c\geq0$, $d>q\geq d/2$。我们证明了 $Lu=f\in L_{p}$ 在有界 $C^{1,1}$-domains, $1 0$ 中的可解性。还获得了与这些算子相关的鞅问题的弱唯一性。
