This is a one-volume edition of Parts I and II of the classic five-volume set The Theory of Functions prepared by renowned mathematician Konrad Knopp. Concise, easy to follow, yet complete and rigorous, the work includes full demonstrations and detailed proofs.
Part I stresses the general foundation of the theory of functions, providing the student with background for further books on a more advanced level.
Part II places major emphasis on special functions and characteristic, important types of functions, selected from single-valued and multiple-valued classes.
