Flow through a porous column

The general equation describing the steady-state flow through a porous column is λu - DxA(Dxθ{symbol}(u) + G(u)) = f, where λ is a nonnegative constant. In this paper existence, uniqueness and comparison results for solutions to the Dirichlet and mixed boundary value problems associated with this eq...
