AbstractWe prove, for 1⩽p<∞ and Ω a polygonal or regular open subset of RN, the density in W1,p(Ω) of a set of regular functions satisfying a homogeneous Neumann condition on the boundary of Ω. We also give applications of this result and a generalization to mixed Dirichlet–Neumann boundary conditions
