Nowadays people usually consider PDEs in weak formulations only, so I have a hard time finding statements about the existence of classical solutions of the Poisson equation with mixed Dirichlet-Neumann boundary conditions.

Maybe someone here can help me and point to a book or article where I can find sufficient conditions on the right hand side that guarantee the existence of a C^2 solution.

A google search on "Dirichlet-Neumann conditions" turn up this:

Thanks. But this only mentions the definition of these boundary conditions. It doesn't give existence conditions for it (but for the Cauchy problem).

I did an extended Google search before I posed the question here, and found nothing useful.

There's a short section in Polyanin's handbook "Linear Partial Differential Equations" covering this case, but it does not appear to be available online. I'm not sure if the material there answers your question.

Thanks. I need to get the book from the library.
