"Bounds for the eigenvalues
of the angular Kerr–Newman Dirac operator"
Streszczenie
In this talk I will describe how to compute sharp intervals of enclosure
for the eigenvalues of matrix differential operators with singular
coefficients. My main concern will be the angular Kerr–Newman Dirac
operator with the possible addition of a smooth perturbation. For the
unperturbed model I will show how to validate existing benchmarks as well
as how to sharpen them by several orders of magnitude. As a main tool I
will employ a pollution-free Galerkin-type method known as the quadratic
method. The research is based on recent joint work with Monika Winklmeier.
Seminarium odbywa się w czwartki w godzinach 10:15–12:00
