A multilevel Newton's method for eigenvalue problems

Yunhui He, Yu Li, Hehu Xie, Chun'guang You, Ning Zhang (2018)

Applications of Mathematics

Similarity:

We propose a new type of multilevel method for solving eigenvalue problems based on Newton's method. With the proposed iteration method, solving an eigenvalue problem on the finest finite element space is replaced by solving a small scale eigenvalue problem in a coarse space and a sequence of augmented linear problems, derived by Newton step in the corresponding sequence of finite element spaces. This iteration scheme improves overall efficiency of the finite element method for solving...
