论文摘要
我们研究了两种技术，用于纠正多边形与域近似相关的几何误差。第一个是在一段时间前引入的\ cite {Bramble1972Procottion}，并导致用于Poisson方程的非对称配方。我们引入了一种新技术，该技术产生了对称配方并具有相似的性能。我们在简单的测试问题上比较了这两种方法。
We study two techniques for correcting the geometrical error associated with domain approximation by a polygon. The first was introduced some time ago \cite{bramble1972projection} and leads to a nonsymmetric formulation for Poisson's equation. We introduce a new technique that yields a symmetric formulation and has similar performance. We compare both methods on a simple test problem.
