# Areas of Research

Department of Mathematics

The seven institutes in the department cover many important research areas in mathematics.

The Department of Mathematics conducts research in many important and modern fields of mathematics. On the one hand, strong fundamental research and the interplay between mathematical fields play a key role. On the other hand, research topics are inspired by interdisciplinary questions in natural, engineering, life and economic sciences, leading to the development of new mathematical methods and foundations.

Members of the Department of Mathematics participate in the **Cluster of Excellence SimTech** and in various **Collaborative Reseach Centers and Research Training Groups**. They maintain strong international and national collaborations, and sustain several large** software projects**.
