About

Erdős Center was established in 2021 in Budapest, Hungary by the
Rényi Institute with the support of HUN-REN (formerly ELKH) in Budapest.

We aim to organize workshops, summer schools and conferences as well as to host visiting researchers within the framework of thematic semesters.

In addition, informal Focused Workshops addressing timely challenges in mathematics are organized in the Summer. 

The Center is located in Reáltanoda utca, the historic center of Budapest, just accross the Rényi Institute. The centre started operating in the spring semester of 2022.  More info about us...

Events

11/28/2024 - 11/30/2024
Rényi Institute, Turán Hall
Spectral problems for planar domains and billiards
The workshop focuses around the questions of spectral rigidity motivated by the famous question: Can you hear the shape of a drum? Recent progress on dynamical spectral rigidity will be discussed.
11/28/2024 - 11/30/2024
Rényi Institute, Erdős Center
Spectral gaps and stochastic exchange models
The mini workshop focuses on methods for obtaining key estimates on sharp lower bounds for the spectral gap of the finite coordinate processes. These are required for the hydrodynamics limit in several fundamental particle systems or energy exchange systems.
01/20/2025 - 01/24/2025
Rényi Institute, main lecture hall
School on Disordered media
The School on Disordered media is part of the Semester on Probability and Statistical Physics. MSc students, PhD students and postdocs are welcome to apply.
01/27/2025 - 01/31/2025
Erdős Center
Workshop on Disordered media
The workshop will cover a wide range of subjects related to statistical physical phenomena in random and disordered media.
03/31/2025 - 04/04/2025
Rényi Institute, Main Lecture Hall
Groups and Geometry School
The school and conference will be devoted to the most diverse aspects of group theory and geometry in their broadest sense.
04/06/2025 - 04/11/2025
Rényi Institute, Main Lecture Hall
Groups and Geometry Workshop
The school and workshop will be devoted to the most diverse aspects of group theory and geometry in their broadest sense.
06/30/2025 - 07/02/2025
Erdős Center
Stochastics and Influences Workshop
The aim of the workshop is to celebrate the impact of the work of Bálint Tóth on the occasion of his 70th birthday. Topics of the workshop include the large-scale behaviour of stochastic and dynamical systems inspired by the questions of statistical physics.

Rényi Institute, main lecture hall
Summer school I: Invitation to complex geometry
During this one week summer school, Eleonora di Nezza (Paris, Sorbonne) and Siarhei Finski (Paris, CNRS) will give introductory talks on Kähler geometry, highlighting recent advances, to a group of non-experts, primarily composed of students and postdocs.

Experience Stories

Account of the winter school on singularities and low-dimensional topology

02/15/2023
Recently, I participated in the Winter school in singularities and low-dimensional topology. This was the opening event of the Erdős Center semester Singularities and low-dimensional topology. The workshop was intended to form a link between low-dimensional topology and singularity theory in the minds of more than a hundred young researchers and PhD-students such as myself.

Optimal Transport on Quantum Structures Workshop

10/07/2022
In the last two weeks of September we were welcome at the Rényi institute for a school and workshop on optimal transport on quantum structures. After a very nice school introducing some of the main ideas in this field, we got to start on the research talks. Matthijs Vernooij

Summer School on Quantum Optimal Transport

09/30/2022
During my visit to the Hungary National museum, I learned that during the cold war Budapest was seen as a city where scholars came together, minds were sparked and conventions where challenged. Well, for at least two weeks in September history seemed to have repeated itself. Robert de Keijzer
