报告题目：Conforming Spectral Methods with Exact Divergence-Free Constraints

报告摘要： In this talk, we construct the C-, Curl- and Div-conforming spectral elements satisfying exact divergence free constraints with the help of variant de Rham complexes together with the Helmholtz-Hodge decomposition. Novel spectral and spectral element methods are then proposed for solving Stokes and Maxwell eigenvalue problems. Finally, numerical experiments are carried out to verify the effectiveness and efficiency of our methods.
