AI总结:

本文分析了混合不连续伽辽金格式求解准线性椭圆问题的稳定性,扩展了BR1、BR2、SIPG和LDG等离散化方案到非线性问题,并证明了单调和全局利普希茨问题的解的唯一性和误差估计的最优性。

摘要:

本文提出了一种分析不连续伽辽金解的通用方法,适用于一般准线性椭圆问题。该方法能够将大多数已知的离散化方案,包括BR1、BR2、SIPG和LDG,扩展到非线性情况,并建立其解的稳定性。在单调和全局利普希茨问题的情况下,我们证明了近似解的存在性和唯一性,以及能量范数和L_2范数中的h-最优误差估计。

英文摘要:

In this manuscript we present an approach to analyze the discontinuous Galerkin solution for general quasilinear elliptic problems. This approach is sufficiently general to extend most of the well-known discretization schemes, including BR1, BR2, SIPG and LDG, to nonlinear cases in a canonical way, and to establish the stability of their solution. Furthermore, in case of monotone and globally Lipschitz problems, we prove the existence and uniqueness of the approximated solution and the $h$-optimality of the error estimate in the energy norm as well as in the $L_2$ norm.
