Until the end of 2023, the BBC + G Seminar (Big Budapest Combinatorics + Geometry Seminar) is the main seminar of the Special Semester on Discrete Geometry and Convexity at the Erdos Center. Most of the lectures will be on Thursday afternoon (16:15 or 14:15pm), in the Big Hall of Rényi Institute.

In the Fall of 2023 the Erdős Center of the Rényi Institute organizes a special semester on Discrete Geometry and Convexity. In the framework of this program, we will run a special seminar, attended by the participants and all members of our institute interested in the subject. 

For a graph \(G=(V,E)\) with edge weight \(w:E\rightarrow \mathbb{R}^+\), a \(t\)-spanner is a spanning subgraph \(H\) such that for all pair of vertices \(u,v\in V\), we have \(d_H(u,v)\leq t\cdot d_G(u,v)\), where \(d_G(u,v)\) denotes the shortest path distance between vertices \(u\) and \(v\) in \(G\).

Graph Drawing and Combinatorial Geometry Workshop

This workshop is mainly devoted to recent developments in Fourier analysis and function spaces.

The summer school is aimed to give an introduction to the theory and the most recent techniques and topics of additive combinatorics dedicated to graduate students and young researchers.

This yearly international workshop brings together young mathematicians, providing in depth introductions to various topics in set theory, leading to questions at the forefront of research.

The topic of the conference is aimed to emphasize the rich interactions between additive combinatorics, harmonic analysis and number theory.

The workshop will be an informal gathering of researchers of related backgrounds (like set theory, dynamics, probability theory, combinatorics, and even theoretical computer science) to cover the latest developments in the area.
