摘要

最近有一篇论文介绍了用离散化网络代替常规网格的网络元法。利用关联网络几何系数，遵循虚拟元框架，提出了一致稳定的数值格式。本文的目的是在适当的假设条件下推导出NEM的收敛理论。我们还得出了基本的误差估计，这是次优的，因为我们必须假设比通常更多的规律性。

Basic convergence theory for the network element method

A recent paper introduced the network element method (NEM) where the usual mesh was replaced by a discretization network. Using the associated network geometric coefficients and following the virtual element framework, a consistent and stable numerical scheme was proposed. The aim of the present paper is to derive a convergence theory for the NEM under mild assumptions on the exact problem. We also derive basic error estimates, which are sub-optimal in the sense that we have to assume more regularity than usual.

期刊介绍： M2AN publishes original research papers of high scientific quality in two areas: Mathematical Modelling, and Numerical Analysis. Mathematical Modelling comprises the development and study of a mathematical formulation of a problem. Numerical Analysis comprises the formulation and study of a numerical approximation or solution approach to a mathematically formulated problem. Papers should be of interest to researchers and practitioners that value both rigorous theoretical analysis and solid evidence of computational relevance.
