Lower bounds for eigenvalues of the Steklov eigenvalue problem with variable coefficients
Yu Zhang, Hai Bi, Yidu Yang
In this paper, using new correction to the Crouzeix-Raviart finite element eigenvalue approximations, we obtain lower eigenvalue bounds for the Steklov eigenvalue problem with vari…
