退化/奇异完全非线性椭圆型方程的Alexandroff-Bakelman-Pucci估计和Harnack不等式

Alexandroff-Bakelman-Pucci estimate and Harnack inequality for degenerate/singular fully non-linear elliptic equations

Cyril Imbert

摘要:

本文研究了非散度型完全非线性椭圆型方程,它在“梯度很小”时是退化的。典型的例子是涉及$m$ -拉普拉斯算子的方程或来自随机控制问题的Bellman-Isaacs方程。我们建立了这类退化椭圆型方程黏性解的Alexandroff-Bakelman-Pucci估计并证明了一个Harnack不等式.

英文摘要:

In this paper, we study fully non-linear elliptic equations in non-divergence form which can be degenerate when "the gradient is small". Typical examples are either equations involving the $m$-Laplace operator or Bellman-Isaacs equations from stochastic control problems. We establish an Alexandroff-Bakelman-Pucci estimate and we prove a Harnack inequality for viscosity solutions of such degenerate elliptic equations.
