Max Planck Institute for Mathematics

From the foundations of information science to string theory and the theory of black holes, from global positioning systems to secure data encryption, the technology of the modern world depends on sophisticated mathematics. In all these examples and in countless others, the mathematics that is used was developed in the course of purely theoretical investigations, and the applications came only later and unexpectedly. It is this more theoretical and foundational side of the field which is primarily studied at the Max Planck Institute for Mathematics. Here research is done in geometry and topology (its more flexible cousin), in number theory and analysis – fields that are centuries old, but that continue to lead to exciting new discoveries and turn out to have surprising connections among each other and to other sciences.

PhD opportunities

This institute has an International Max Planck Research School (IMPRS):

IMPRS for Moduli Spaces

In addition, there is the possibility of individual doctoral research. Please contact the directors or research group leaders at the Institute.

Fields Medal awarded to Peter Scholze

New Director of the Max Planck Institute for Mathematics awarded the highest distinction in Mathematics


For many, mathematics is nothing more than an accumulation of abstract formulas and dry recipes for calculating. Not so for Friedrich Hirzebruch, Founding Director of the Max Planck Institute for Mathematics in Bonn, Germany. He had already succumbed to the beauty of the subject in his youth. As the “doyen of German post-war mathematics,” Hirzebruch made this city on the Rhine an attractor for researchers the world over.

Johann Sebastian Bach, Le Corbusier and Maurits Escher: Mathematics has influenced many a creative genius. But also mathematics itself contains an element of beauty.

Starting with completely abstract structures, mathematicians develop new theories and models that precisely formulate and describe real properties of the real world.

Topological periodic homology

2018 Thomas; Nikolaus


It is a classical algebraic problem to study solutions of polynomial equations. Since this can be very hard, people have invented certain algebraic invariants, called cohomology theories, to get a qualitative picture. Crystalline cohomology is one of these cohomology theories which is especially important in counting solutions over finite fields. It is an algebraic invariant, but it has recently been possible to express crystalline cohomology in terms of a topological invariant - called topological periodic homology. This leads to natural generalizations, extensions and computations.


Borcherds products

2017 Kaiser, Christian


After introducing elliptic modular forms we consider Borcherds products as singular theta lifts on orthogonal groups. Finally we discuss a characterization of Borcherds products by symmetries.


Quantum mechanics on a graph

2016 Mnev, Pavel


We discuss the problem of counting paths going along the edges of a graph as a toy model for Feynman’s path integral in quantum mechanics.


Diophantine equations

2015 von Känel, Rafael; Matschke, Benjamin


We discuss certain classical Diophantine equations and we explain how geometry can help to understand their solutions. In particular we consider some highlights in the field of Diophantine equations, including Faltings' resolution of the Mordell conjecture and Wiles' proof of Fermat's last theorem. We also discuss a project at the MPIM Bonn which combines the methods of Faltings and Taylor-Wiles in order to make some progress concerning the classical problem of finding all squares and cubes of given difference.


Deformations of foliations

2014 Vogel, Thomas


We discuss an application of contact topology to the space of foliations by surfaces on 3-manifolds. Without further geometric restrictions on the foliation, the connected components of the space of foliations are well understood. In contrast to this, if one requires that all foliations under consideration are taut, then the space of these foliations is more complicated. So far, its connected components are classified only in few special situations.
