建立了极值方程在Ω中有界区域的子解的广义极大值原理,其中[ILM 0003]是依赖于正参数的Pucci极值算子,可以是无界的.更精确地说,它表明,如果u是上述极值方程的一个子解,则对于某些其中C和q依赖于。这里的证明是通过一个次线性函数表示,而不使用经典的线性理论。该结果是Fabes-Stroock结果到完全非线性方程的推广。
A generalized maximum principle is established for subsolutions inΩa bounded domian in of the extremal equations where [ILM0003is the Pucci extremal operator depending on positive parameters and can be unbounded. More precisely, it is shown that if u is a subsolution of the above extremal equations, then for some where C and q depend on . The proof here runs through a sublinear functional representation without employing classical linear theory. The result is a generalization of the Fabes—Stroock result to fully nonlinear equations.
