The Agmon-Miranda maximum principle for the polyharmonic equations of all orders is shown to hold in Lipschitz domains in ℝ3. In ℝn, n≥4, the Agmon-Miranda maximum principle and Lp-Dirichlet estimates for certain p>2 are shown to fail in Lipschitz domains for these equations. In particular if 4≤n≤2 m+1 the Lp Dirichlet problem for Δm fails to be solvable for p>2(n−1)/(n−3).
