Approximating evolution operators of linear delay equations: a general framework for the convergence analysis

Alessia andò, Giusy Bosco, Dimitri Breda +1

We consider the problem of discretizing evolution operators of linear delay equations with the aim of approximating their spectra, which is useful in investigating the stability pr…
