Abstract: We prove a well-posedness result in the class $ {W^{2,p}} \cap W_0^{1,p}$ for the Dirichlet problem

$\displaystyle \left\{ {\begin{array}{*{20}{c}} {Lu = f} & {{\text{a.e.}}\;{\tex... ...Omega }, \\ {u = 0} & {{\text{on}}\;\partial \Omega }. \\ \end{array} } \right.$

We assume the coefficients of the elliptic nondivergence form equation that we study are in $ {\text{VMO}} \cap {L^\infty }$ .
