A Nonnested Augmented Subspace Method for Eigenvalue Problems with Curved Interfaces
Haikun Dang, Hehu Xie, Gang Zhao +1
In this paper, we present a nonnested augmented subspace algorithm and its multilevel correction method for solving eigenvalue problems with curved interfaces. The augmented subspa…
