Computing defective eigenpairs in parameter-dependent eigenproblems

Frank Adams Room 1, Alan Turing Building,

The requirement to compute Jordan blocks for multiple eigenvalues arises in a number of physical problems, for example panel flutter problems in aerodynamical stability, the stability of electrical power systems, and in quantum mechanics. We introduce a general method for computing a 2-dimensional Jordan block in a parameter-dependent matrix eigenvalue problem based on the so called Implicit Determinant Method.
This is joint work with Alastair Spence (Bath).
