An elliptic problem in dimension N with a varying drift term bounded in LN

The present paper is devoted to study the asymptotic behavior of a sequence of linear elliptic equations with a varying drift term, whose coefficients are just bounded in LN (Ω), with N the dimension of the space. It is known that there exists a unique solution for each of these problems in the Sobo...

Sumario:The present paper is devoted to study the asymptotic behavior of a sequence of linear elliptic equations with a varying drift term, whose coefficients are just bounded in LN (Ω), with N the dimension of the space. It is known that there exists a unique solution for each of these problems in the Sobolev space H10(Ω). However, because the operators are not coercive, there is no uniform estimate of the solutions in this space. We use some estimates in [2], and a regularization obtained by adding a small nonlinear first order term, to pass to the limit in these problems.
