Introduction to Hydrodynamic Stability (Cambridge Texts in Applied Mathematics)
"Each chapter concludes with a large body of exercises (120 in all), of varying degrees of difficulty. These will be a boon for the instructor who is charged with finding suitable questions for assessment purposes. I found this book to be a very readable introductory textbook, and one which will make an excellent addition to the library of anyone contemplating a graduate level course in hydrodynamic stability."
