报告题目: Efficient spectral methods for elliptic PDEs in domains of complex geometry

摘要: An efficient spectral solver is developed for elliptic partial differential equations in complex domains. By a fictitious domain approach, an extended problem is built by embedding the original domain into an enlarged and regular one. Two types of Petrov-Galerkin formulations with special trial and test functions are presented and analyzed. A fast algorithm is developed for solving the corresponding linear system. We present ample numerical results to show the efficiency and accuracy of this approach.
