Power contraction of RAS with local impedance problems for the Helmholtz equation

报告题目：Power contraction of RAS with local impedance problems for the Helmholtz equation报告摘要：The Helmholtz equation is notoriously difficult to solve, especially for the case of high wavenumber. The Restricted Additive Schwarz preconditioner with local impedance problems (often called the ORAS method) is arguably the most successful one-level...

非定常Ginzburg-Landau方程的保结构有限元算法

报告题目：非定常Ginzburg-Landau方程的保结构有限元算法报告摘要：对于时间规范下的非定常Ginzburg-Laudau 方程，我们提出了一类物理边界条件下的非线性有限元算法，避免了因额外边界条件导致的非物理数值现象。对该非线性格式我们设计了数值有效的预条件子，并分析了其有效性，将该非线性格式的计算量降至线性解耦格式计算量同一量级的同时保证了数值能量的稳定性。我们还提出了一类保持无条件能量耗散和离散极值原理的解耦...
