Kathrin Bringmann

Kathrin Bringmann ( born May 8, 1977 in Münster ( Westphalia ) ) is a German mathematician who deals with number theory and modular forms.

Bringmann studied mathematics and theology at the University of Würzburg, the state exam 's degree in 2002 and a diploma in mathematics in 2003. 2004 she received her doctorate in Winfried Kohnen at the University of Heidelberg ( Applications of Poincaré Series on Jacobi groups). 2004 to 2007 she was an Assistant Professor at the University of Wisconsin (Madison ) at Ken Ono, then at the University of Minnesota ( Minneapolis ), and since 2008 professor at the University of Cologne.

With Ken Ono developed a theory of mock theta functions of Ramanujan, who told this all but the last of his "problems" before his death Godfrey Harold Hardy in a ( incomplete obtained ) letter in the form of some power series development formulas. Ono and Bringmann embedded the mock theta functions in the theory of special modular forms ( Maass forms), among which they showed that there are infinitely many, and thus achieved a breakthrough in a long open problem circle, underline its importance, among others, by Freeman Dyson been. Specifically, they demonstrated a presumption of George Andrews ( 1966) on the exact form of the coefficients of the series expansion of the mock- theta function. The mock theta functions also have connections to the theory of partitions in number theory, from the exact form of the coefficients of the formulas obtained for the number of partitions even and odd rank.

In 2009 she won the SASTRA Ramanujan Prize and in 2009 the Alfried Krupp Prize for Young University Teachers.
