The Dirichlet problem in Lipschitz domains with boundary data in Besov spaces for higher order elliptic systems with rough coefficients

Vladimir Maz'ya, Marius Mitrea, Tatyana Shaposhnikova

We settle the issue of well-posedness for the Dirichlet problem for a higher order elliptic system $\mathcal{L}(x,D_x)$ with complex-valued, bounded, measurable coefficients in a…
