摘要:

In the present paper, we consider elliptic equations with nonlinear and nonhomogeneous Robin boundary conditions of the type

where f and g are the element of L1(Ω) and L11), respectively. We define a notion of renormalized solution and we prove the existence of a solution. Under additional assumptions on the matrix field B we show that the renormalized solution is unique.
