We show that if u is a solution to a linear elliptic differential equation of order 2m≥2 in the half-space with t-independent coefficients, and if u satisfies certain area integral estimates, then the Dirichlet and Neumann boundary values of u exist and lie in a Lebesgue space L p (ℝ n ) or Sobolev space W ˙ ±1 p (ℝ n ). Even in the case where u is a solution to a second order equation, our results are new for certain values of p.
