Intended for advanced undergraduates and graduate students, this concise text focuses on the convergence of real series. Topics include functions and limits, real sequences and series, series of non-negative terms, general series, series of functions, the multiplication of series, infinite products, and double series. 1959 edition.
Great pace and level of detail. Sometimes the intuition for certain choices was beyond me (particularly dealing with the gamma function) and more could be done for realising which test might be best to use. Otherwise a great text that has aged well.
