 Perturbation theory isn't usually considered in the complex plane. 
-But when it is, we have seen that a lot can be learnt about the performance of perturbation theory on the real axis.
+But when it is, a lot can be learnt about the performance of perturbation theory on the real axis.
 These insights can allow incredibly accurate results to be obtained using only the lowest-order terms in a perturbation series.
 Yet perturbation theory represents only one method for approximating the exact energy, and few other methods
 have been considered through similar complex non-Hermitian extensions.
