A Variational Principle for Block Operator Matrices and its Application to the Angular Part of the Dirac Operator in Curved Spacetime
Monika Winklmeier
The operator associated to the angular part of the Dirac equation in the Kerr-Newman background metric is a block operator matrix with bounded diagonal and unbounded off-diagonal e…

On the local energy decay of solutions of the Dirac equation in the non-extreme Kerr-Newman metric, I
Monika Winklmeier, Osanobu Yamada
We investigate the local energy decay of solutions of the Dirac equation in the non-extreme Kerr-Newman metric. First, we write the Dirac equation as a Cauchy problem and define th…
