论文摘要
我们引入了一种均匀的多机方法,从某种意义上说,它在所有级别上都使用相同的HDG离散化方案来进行泊松方程。特别是,我们在椭圆规律性的假设下构建了稳定的注射算子,并证明了该方法的最佳收敛性。数值实验强调了我们的分析结果。
We introduce a homogeneous multigrid method in the sense that it uses the same HDG discretization scheme for Poisson's equation on all levels. In particular, we construct a stable injection operator and prove optimal convergence of the method under the assumption of elliptic regularity. Numerical experiments underline our analytical findings.
