Discretization in Geometry and Dynamics
SFB Transregio 109

The Collaborative Research Center (SFB TRR) 109 reseraches the discretization of geometric structures and dynamic processes. That means, that they dismantle smooth geometric objects, such as curved surfaces, into simple basic elements, or reduce continual processes, such as the flight paths of satellites, into their partial steps.


Collaborative Project: Discretization in Geometry and Dynamics (DGD)

This transregional research project is financed by the German Reserach Foundation (DFG) and is headed by the TU Berlin with the TUM as the partner university. Leading scientists from the FU Berlin, TU Graz, TU Wien and IST Austria complete the group. In a total of 17 projects, 120 mathematicians work on questions concerning the discretization of geometric structures and dynamic processes as well as in the area of computation.

Discretization enables the calculation and analsysis on computers and is used in areas such as computer graphics, digital signal processing and numerical simulations.

Mathematical methods as technology of the future

"Previous methods only allow approximate values, which are no longer sufficient for many tasks today," explains spokesman Alexander Bobenko, Professor of Geometry at the TU Berlin. "In order to achieve better results, we therefore want to find, investigate and apply so-called structure-preserving discretizations. One could also say that we no longer want to discretize individual equations, but rather the underlying theories.

Specifically, the researchers are investigating discretizations for which there are no structural differences in important aspects to corresponding smooth surfaces or continuous dynamic processes. One subproject, for example, deals with the decomposition of curved surfaces into flat squares. This allows the construction of a curved glass roof - with easy to manufacture construction elements. This makes it possible to realize a cost-effective and aesthetically pleasing architectural idea.

DFG funds a 3rd research period of the SFB TRR 109

The Collaborative Research Center/Transregio 109 "Discretization in Geometry and Dynamics" will enter its third funding phase in 2020: until 2024 the DFG will finance the project with a total of more than 7 million euros. In 2012, the TUM, together with the Technische Universität Berlin, received for the first time approximately 6 million euros from the DFG for the first 4 years of the mathematical research project. In 2016, the project was extended by 4 years with DFG funding of 7 million euros.

The area "computation" has been significantly extended in the 2nd research period, with a total of seven subprojects, aiming to keep abreast of current developments. The field of public relations also receives more support, particularly in the areas of computer-aided media and film. The support of young researches remains a central objective of the research work, with numerous research jobs for doctorate and postdoctorate students financed by the DFG. 

In research period 3, the scientists of the SFB/TRR want to bring geometry and dynamics even closer together. Structure-preserving discretizations remain the main topic. Computer scientists at TUM strengthen application-oriented research. Exciting research topics are among others: 

  • discrete conformal models in geometry and mathematical physics
  • rigidity of spin systems, discrete structures in fluids
  • structure-preserving discretizations of dynamic systems 
  • geometric structures in architecture
