In this paper, we present a normwise perturbation theory for the regular generalized eigenproblem Ax = λBx, when λ is a semi-simple and finite eigenvalue, which departs from the classical analysis with the chordal norm [9]. A backward error and a condition number are derived for a choice of flexible
Operator regularization is a symmetry preserving regularization procedure to all orders of perturbation theory that avoids explicit divergences. At one-loop order it is det H which is regularized, where H is an operator appearing in the theory. For some theories it is not possible to treat det H dir
