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.
