Elliptische Funktionen und Modulformen

From the reviews of the second edition: „The book under review is the basically unaltered second edition of the original, whose popularity at German-speaking universities has grown continually over the past decade. … Altogether, the present second edition of this well-established, highly cultured textbook on elliptic functions and modular forms comes with … remarkable and appropriate improvements, amplifications, and up-datings. … this text breathes the inimitable spirit of the late Max Koecher, a great mathematical researcher and teacher, and his co-author’s effort at communicating and preserving it must be highly acknowledged.“ (Werner Kleinert, Zentralblatt MATH, Vol. 1129 (7), 2008)
