Let D be a bounded domain in ℝn with n ⩾ 2. For a function f on ∂D we denote by ℋD f the Dirichlet solution, for the Laplacian, of f over D. It is classical that if D is regular, then ℋD maps the family of continuous boundary functions to the family of harmonic functions in D continuous up to the boundary ∂D. We show that improved continuity of a boundary function f ensures improved continuity of ℋD f in the context of general modulus of continuity.
