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...

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
