Elliptic equations in Sobolev spaces with Morrey drift and the zeroth-order coefficients

We consider elliptic equations with operators L = a i j D + b − c L=a^{ij}D_{ij}+b^{i}D_{i}-c alttext="a"> encoding="application/x-tex">a being almost in VMO, alttext="b"> encoding="application/x-tex">b Morrey class containing d"> d encoding="application/x-tex">L_{d} , and alttext="c greater-than-or-equal-to 0"> ≥ encoding="application/x-tex">\lambda u-Lu=f whole space for any greater-than > >0 Weak uniqueness martingale problem associated such is also discussed.
