Abstract

The Meyer’s estimate of solutions to Zaremba problem for second-order elliptic equations in divergent form

Highlights

  • In this paper we estimate solutions to the Zaremba problem for elliptic equations in bounded Lipschitz domain D ∈ Rn, where n > 1, of the formL u := div(a(x)∇u) (1)with uniformly elliptic measurable and symmetric matrix a(x) = {ai j (x)}, i.e. ai j = a ji and n α−1|ξ|2 ≤ ai j (x)ξi ξj ≤ α|ξ|2 for almost all x ∈ D and for all ξ ∈ Rn . (2) i, j =1Below we assume that the set F ⊂ ∂D is closed and denote G = ∂D \ F

  • We assume that the set F ⊂ ∂D is closed and denote G = ∂D \ F

  • In the case of homogeneous Dirichlet problem for (3) with right-hand side f ∈ Lp (D), where p > 2, the increased integrability of the gradient of solutions to divergent uniformly elliptic equations with measurable coefficients on the plane follows from the results of [3]
