摘 要：

In this talk, new progress and advances are reported on the application of the Lagrange elements which are nodal-continuous and H1-conforming to the Maxwell eigenproblem. We have proven the discrete compactness property for all the Lagrange elements of any order in the finite element discretization of the classical and standard double curl variational formulation of the Maxwell eigenproblem. These are the first and only known results so far. The open problem on the discrete compactness of the Lagrange elements when using the same variational formulation as the Nedelec elements had been existing for more than thirty years. Theoretical results and numerical results are presented.
