摘要
In this paper, we discuss the asymptotic behavior of the positive solutions of the problem -Deltau=au-bu(p), u\(partial derivativeOmega)=0 as p-->1+0 and as p-->infinity. We show that, for each case, the behavior is determined by a limiting problem. Moreover, the limiting problem is of free boundary nature when p-->infinity.
