文摘

In this paper a class of N-dimensional second-order linear elliptic equations with a drift is studied. When the drift belongs to L 2 the existence of a renormalized solution is proved. There is also uniqueness in the class of the renormalized solutions modulo \(L^{\infty }\), but the uniqueness is violated when the drift equation is regarded in the distributions sense. Then, considering a sequence of oscillating drifts which converges weakly in L 2 to a limit drift in L q , with q > N, the homogenization process makes appear an extra zero-order term involving a non-negative Radon measure which does not load the zero capacity sets. This extends the homogenization result obtained in [3] by relaxing the equi-integrability of the drifts in L 2.
