带对流项的奇异拟线性椭圆型问题

Singular quasilinear elliptic problems with convection terms

Umberto Guarnotta

摘要:

在本文中,我们提出了一些最近的结果,存在性,唯一性和多重性的拟线性椭圆型方程和系统,表现出奇异和对流反应项。边界条件(狄利克雷,诺依曼,或罗宾)的重要性也进行了讨论。通过次上解和截断技巧,不动点理论,非线性正则性和集值分析,而唯一性和多重性得到单调性参数。

英文摘要:

In this paper we present some very recent results regarding existence, uniqueness, and multiplicity of solutions for quasilinear elliptic equations and systems, exhibiting both singular and convective reaction terms. The importance of boundary conditions (Dirichlet, Neumann, or Robin) is also discussed. Existence is achieved via sub-supersolution and truncation techniques, fixed point theory, nonlinear regularity, and set-valued analysis, while uniqueness and multiplicity are obtained by monotonicity arguments.
