Efficient solution of the lowest eigenmodes is studied for a family of related eigenvalue problems with common $2\times 2$ block structure. It is assumed that the upper diagonal block varies between different versions while the lower diagonal block and the range of the coupling blocks remains unchanged. Such block structure naturally arises when studying the effect of a subsystem to the eigenmodes of the full system. The proposed method is based on interpolation of the resolvent function after… Expand

A purely algebraic look at the automated multilevel substructuring method is taken and it is explained that it can be viewed as a combination of three ingredients: a first order expansion to a nonlinear eigenvalue problem that approximates the restriction of the original eigenproblem on the interface between the subdomains, judicious projections on partial eigenbases, and recursivity.
