We consider a nonlinear elliptic Dirichlet problem driven by the -Laplacian and a reaction consisting of a parametric singular term plus a Carathéodory perturbation which is -linear as . First we prove a bifurcation-type theorem describing in an exact way the changes in the set of positive solutions as the parameter moves. Subsequently, we focus on the solution multifunction and prove its continuity properties. Finally we prove the existence of a smallest (minimal) solution and investigate the monotonicity and continuity properties of the map .

我们考虑一个非线性椭圆Dirichlet问题,它由 -拉普拉斯算子和由参数奇异项加上Carathéodory扰动组成的反应 这是 -线性为 。首先,我们证明分叉型定理,以精确的方式描述正解集中的变化作为参数动作。随后,我们着重于解决方案的多功能性并证明其连续性。最后,我们证明了最小(最小)解的存在 并研究地图的单调性和连续性 。
