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

06/29/2026 - 07/03/2026
Summer School on Algebraic Curves
The summer School concentrates mostly on topological aspects, like classification and the genus formula for projective curves, algebraic knots and links, algebraic plane curve singularities, monodromy, Milnor number and fibers.
07/06/2026 - 07/09/2026
Rényi Institute, Erdős Center
Focused Workshop on dimension drop for analytic Iterated Function Systems
The objective of the Focused Workshop is to bring together experts from dynamical systems, harmonic analysis, and geometric measure theory in order to facilitate progress on the dimension drop conjecture by gaining a deeper understanding of the connections between these areas.
07/13/2026 - 07/15/2026
Rényi Institute
Logic, Relativity and Beyond (LRB26)
The aim of this conference series, which take place once every 2 or 3 years, is to attract and bring together mathematicians, physicists, philosophers of science, and logicians from all over the world interested in these and related areas to exchange new ideas, problems and results.
07/13/2026 - 07/17/2026
Rényi Institute, Erdős Center
Focused Workshop on Trace formulae on quotients of hermitian symmetric spaces
Trace formulas are a central tool to understand families of automorphic forms. The workshop will gather a team of young and dynamic researchers to foster new projects to obtain arithmetic statistics on automorphic forms for such higher rank groups using the newly available trace formulas.
07/27/2026 - 07/31/2026
Rényi Institute, Erdős Center
Focused Workshop on Asymptotic Tensor Parameters
The aim of this workshop is to discuss and make progress on open problems related to properties and applications of asymptotic tensor parameters.
08/24/2026 - 08/28/2026
Rényi Institute, Main Lecture Hall
Simons School on Moduli of curves, abelian varieties and K3 surfaces
Jointly organized with the RTG Berlin-Hannover "From geometry to numbers: Moduli, Hodge theory, rational points" financed by the DFG. Part of the thematic semester Algebraic Geometry (August-December 2026) hosted by the Erdős Center.
10/05/2026 - 10/09/2026
Rényi Institute, Main Lecture Hall
Simons School on Higher dimensional varieties
The 4 lecture series of the School will focus on modern techniques in the classification theory of higher dimensional algebraic varieties, highlighting connections to K-stability and singularity theory. Part of the thematic semester Algebraic Geometry (August-December 2026) hosted by the Erdős Center.
10/12/2026 - 10/16/2026
Rényi Institute, Main Lecture Hall
Workshop on Higher dimensional varieties
The Workshop will focus on modern techniques in the classification theory of higher dimensional algebraic varieties, highlighting connections to K-stability and singularity theory. Part of the thematic semester Algebraic Geometry (August-December 2026) hosted by the Erdős Center.
01/18/2027 - 01/22/2027
Rényi Institute, Main Lecture Hall
Simons School on Order and Structure in Geometry
Ordered structures arise naturally in many problems and proofs in discrete geometry. For example, the unit distance problem for convex polygons stimulated the extremal theory of 0–1 matrices. Similarly, the study of point-set configurations, known as the study of order types, plays an important role in geometric problems such as rectilinear crossing numbers and the happy ending problem.

Simons School on Ordered Combinatorial Structures
In extremal, probabilistic, and structural combinatorics, many objects and arguments possess natural orderings. For example, the Erdős–Hajnal stepping-up argument for hypergraph Ramsey numbers processes vertices one by one according to a fixed order. Similarly, the resolution of the Stanley–Wilf conjecture relies on 0–1 matrices, which may be viewed loosely as ordered analogues of bipartite graphs.

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.

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
