Time asymptotics of e−ith(κ) for analytic matrices and analytic perturbation theory
M. Klein, J. Rama · Asymptotic Analysis · 2014
In quantum mechanics the temporal decay of certain resonance states is associated with an effective time evolution e−ith(κ) , where h(·) is an analytic family of non-self-adjoint matrices. In general the corresponding resonance states do not decay ex
