....stability. In fact, 73) is not true in general if the semigroup is only strongly continuous, 3] 6] Looking for strong stability, we need to assume that the rational function r is strongly A(#) stable, i.e. we assume in addition that r(#) 0. Then one can prove , t n 0, 74) see [9]. This opens the possibility of proving error estimates analogous to those of Theorem 2. For a similar result for a particular class of time discretizations but with variable timesteps, see [8] ....
