Research in the fields

Analysis and Systems Theory Group

Mandy Neuendorf
Main research areas of the group

Prof. Dr. Achim Ilchmann has been head of the group "Analysis and Systems Theory" since 2000. His research area as Professor of Analysis and Dynamical Systems is the robust control of nonlinear systems with applications to biotechnological processes and electric motors. He has spent several years researching and teaching in England, always reading mathematics for mathematicians as well as engineers. He also regularly gives lectures on philosophical problems in mathematics.

Applied Functional Analysis Group

Carsten Trunk
Main research areas of the group

Prof. Dr. Carsten Trunk is interested in a special structure: While distances are usually positive, he is interested in what happens if you also allow negative distances. In this case, for example, two different points can have a distance of zero from each other. Surprisingly, such spaces appear in many problems, such as modern quantum mechanics or hydrodynamics. Besides his research in the field of applied functional analysis, Prof. Trunk has been giving lectures for engineers for many years.

Group for Discrete Mathematics and Algebra

Michael Reichel
Main research areas of the group

Prof. Dr. Matthias Kriesell is Professor of Discrete Mathematics and Algebra.

  • Structure of finite graphs Decomposition and coloring of graphs, list coloring of special graph classes
  • Algorithms on graphs
  • Graph theoretical methods in chemistry and physics
  • Structure theory of symplectic modules
 

Large Networks and Random Graphs Group

Michael Reichel
Main research areas of the group

Large Networks and Random Graphs is an endowed professorship of the Carl Zeiss Foundation. In his research, Professor Person searches for patterns in large discrete structures that appear chaotic. This often involves the interplay of structure and randomness as a means of proof. This also has application references in computer science, e.g. in property testing.

Group for Mathematical Methods in Operations Research

G. Eichfelder
Main research areas of the group

The group Mathematical Methods in Operations research, headed by Professor Gabriele Eichfelder, works on recent research topics in the field of mathematical optimization. This includes theoretical examinations of optimization problems as well as the development of numerical algorithms for specific problem classes.  The focus is, among others, on optimization problems with multiple objectives and on non-convex optimization such as mixed integer nonlinear problems.

Optimization-based Control Group

Michael Reichel
Main research areas of the group

Prof. Dr. Karl Worthmann is Heisenberg Professor for Optimization-based Control. The English term "control" in the denomination of his field includes both open-loop control and closed-loop control. It is precisely the interplay between open-loop and closed-loop control that is at the heart of modern methods of nonlinear systems theory such as Model Predictive Control (MPC). Karl Worthmann's research uses methods from various mathematical fields, including modeling, optimization, and numerics. In addition, there is a wide range of applications in industry and business, e.g. in robotics, medical technology or in the course of the energy transition.

Group for Probability Theory and Mathematical Statistics

Michael Reichel
Main research areas of the group

Stochastics is the branch of mathematics that deals with randomness. On the one hand, probability theory models random phenomena mathematically in order to subsequently subject them to a precise analysis; on the other hand, mathematical statistics develops methods for the evaluation of data that quantify the uncertainty due to random influences in data collection. In our research we deal with theoretical as well as applied topics. Keywords are: Statistics of geometric objects, applications of measure concentration inequalities in statistics, especially for compressive sensing, analysis of stochastic Petri nets.

 

Teaching Group Mathematics

Michael Reichel
Main research areas of the group

Prof. Dr. Thomas Böhme is an associate professor at the Institute of Mathematics and head of the mathematics teaching group. His research areas are graph theory, game theory and their applications in programming. He gives mathematics lectures for engineering students.
