Even if solid fuels, fossil energy resources and mineral commodities are non-renewable, the extracted metals can to a large extent be recycled and used again and again. Although the stock of these secon

Elliptic Problems with Nonhomogeneous Differential Operators and Multiple Solutions, Moreover, a complete sign information is available: two positive solutions, a negative solution and a nodal (sign-changing) solution. Finally, we provide a theorem guaranteeing the existence of a positive solution for a problem involving the .-Laplacian operator ., with ., and a nonlinearity depending on the solution and its gradient.
