Abstract. Let Ω be a bounded domain in C n such that Ω has piecewise smooth boudnary. We discuss the solvability of the Cauchy-Riemann equationwhere α is a smooth ∂-closed (p, q) form with coefficients C ∞ up to the bundary of Ω, 0 ≤ p ≤ n and 1 ≤ q ≤ n. In particular, Equation (0.1) is solvable with u smooth up to the boundary (for appropriate degree q) if Ω satisfies one of the following conditions: i) Ω is the transversal intersection of bounded smooth pseudoconvex domains. ii) Ω = Ω 1 \ Ω 2 where Ω 2 is the union of bounded smooth pseudoconvex domains and Ω 1 is a pseudoconvex convex domain with a piecewise smooth boundary. iii) Ω = Ω 1 \ Ω 2 where Ω 2 is the intersection of bounded smooth pseudoconvex domains and Ω 1 is a pseudoconvex domain with a piecewise smooth boundary. The solvability of Equation (0.1) with solutions smooth up to the boundary can be used to obtain the local solvability for ∂ b on domains with piecewise smooth boundaries in a pseudoconvex manifold.Let Ω be a bounded domain in C n such that Ω has a piecewise smooth boundary. In this paper we study the solvability of the Cauchy-Riemann equationwhere α is a smooth ∂-closed (p, q) form with coefficients C ∞ up to the boundary of Ω, 0 ≤ p ≤ n and 1 ≤ q ≤ n. In particular, we prove that Equation (0.1) is solvable with u smooth up to the boundary (for appropriate degree q) if Ω satisfies one of the following conditions: i) Ω is the transversal intersection of bounded smooth pseudoconvex domains. ii) Ω = Ω 1 \Ω 2 , where Ω 2 is the union of bounded smooth pseudoconvex domains and Ω 1 is a pseudoconvex domain with a piecewise smooth boundary.iii) Ω = Ω 1 \ Ω 2 , where Ω 2 is the intersection of bounded smooth pseudoconvex domains and Ω 1 is a pseudoconvex domain with a piecewise smooth boundary.The boundary regularity problem for ∂ has been studied extensively by two very different methods: by L 2 a priori estimates and by the integral kernel approach.
