研究了具有零Dirichlet边界条件的退化椭圆型方程λ pu + uq−1(1 − ur)= 0,其中λ为正参数,2 &lt;< q and r >p0,在三个方面:极大解的存在性,极大解与λ的依赖性和解的多重性.
The degenerate elliptic equation λ∆pu + uq−1(1 − ur) = 0 with zero Dirichlet boundary condition, where λ is a positive parameter, 2 < p < q and r > 0, is studied in three aspects: existence of maximal solution, λdependence of maximal solution and multiplicity of solutions.
