Abstract:

For higher order inhomogeneous elliptic systems (polyharmonic equations and biharmonic equations) with real constant coefficients on a bounded Lipschitz domain, we investigate sufficient conditions that the ranges of $p$ must satisfy in order for the $W^{\ell,p}$ estimates for weak solutions of Dirichlet problems to be true.
