Eberhard Freitag (19 May 1942 in Mühlacker) is a German mathematician, specializing in complex analysis and especially modular forms.
Freitag studied from 1961 mathematics, physics and astronomy at Heidelberg University, where he received in 1964 his Diplom and in 1966 his Ph.D. (promotion), supervised by Hans Maaß (and also Albrecht Dold), with thesis Modulformen zweiten Grades zum rationalen und Gaußschen Zahlkörper, published in Sitzungsberichte Heidelberger Akad. Wiss. 1967. From 1964 he was a research assistant at the Mathematischen Institut in Heidelberg, where he received at the end of 1969 his habilitation and became there a Privatdozent and in 1970 a scientific advisor. In 1970–1971 he was a visiting professor at Johann-Wolfgang-Goethe-Universität Frankfurt am Main. In 1973 he became a professor ordinarius at the University of Mainz. In 1977 he became a professor ordinarius at Heidelberg University, where from 1991 to 1993 he was the dean of the Faculty of Mathematics.
Freitag's research (like that of his teacher Maaß) deals primarily with the theory of modular forms, but approaches modular forms via algebraic geometry. Among other work, Freitag described this theory in two monographs published by Springer Verlag in Grundlehren der mathematischen Wissenschaften. These two books and the first volume of his series on function theory are standard references. In 1974 in Vancouver he was an Invited Speaker of the ICM with talk Singularitäten von Modulmannigfaltigkeiten und Körper Automorpher Funktionen. In 1998 he proved with Rainer Weissauer and Richard Borcherds the existence of a Siegel cusp form of degree 12 and weight 12 using the theta series associated with the 24 Niemeier lattices of dimension 24.
