New approaches to large scale eigenanalysis

The past few years have seen significant advances in our abilities to compute partial eigendecompositions of large matrices. These new approaches have led to critical advances in several application areas including computational chemistry, semi-conductor laser design, linear stability analysis, and reduced basis techniques for large state space control systems.

This talk will survey some of these new techniques. We shall discuss the implicitly restarted Arnoldi method which is the basis for the software package ARPACK and then introduce some extensions of those ideas for the generalized eigenvalue problem that do not require accurate solution of shift-invert equations.
