Abstract
J P Killingbeck London: Butterworths 1975 pp 224 price £9 The title of this book is somewhat misleading (as the author himself admits) because half the book is about the mathematical background to Hilbert spaces and all that – interesting, but I doubt if many readers will be tempted to venture any deeper into Hilbert space. The rest of the book, about perturbation methods and group theory is useful, and has destroyed some of my misconceptions about the convergence of perturbation series.
