The Berlin Mathematics Research Center MATH+

MATH+ is a cross-institutional and interdisciplinary Cluster of Excellence based in Berlin. It sets out to explore and further develop new approaches in application-oriented mathematics. Emphasis is placed on mathematical principles for using ever larger amounts of data in life and material sciences, in energy and network research, and in the humanities and social sciences.

MATH+ is funded by the Deutsche Forschungsgemeinschaft (DFG, German Research Foundation) for a first period of seven years since January 2019. It is a joint project of the three major universities in Berlin—Freie Universität Berlin, Humboldt-Universität zu Berlin, and Technische Universität Berlin—as well as the Weierstrass Institute for Applied Analysis and Stochastics (WIAS) and the Zuse Institute Berlin (ZIB). MATH+ continues the success stories of the renowned Research Center Matheon and the Graduate School Berlin Mathematical School (BMS).
