New trends in arithmetic combinatorics and related fields, Instituto de Matemáticas de la Universidad de Granada, Granada, June 1-5, 2025.
Arithmetic combinatorics has kept developing and diversifying its topics to the present day. In particular, the last five years, and especially 2023, have seen outstanding advances. This workshop will bring together many world-leading researchers who are working at the cutting edge of these latest developments across several fields.

The 8th Workshop on Design Theory, Hadamard Matrices and Applications (Hadamard 2025), Sevilla, May 26-30, 2025.
The purpose of the workshop is to bring together researchers and students interested in design theory, especially as it relates to Hadamard matrices and their applications, as well as in related areas in coding theory, association schemes, sequences, finite geometry, difference sets, quantum information theory, theoretical physics and computer security. The audiences would learn about the latest developments in these areas, discuss the latest findings, take stock of what remains to be done on classical problems and explore different visions for setting the direction for future work. Hadamard 2025 is the eighth in a series of conferences.

Barcelona Discrete Mathematics Meeting 2025, Centre de Recerca Matemàtica, January 30, 2025.

The aim is to bring together these different groups in the area and host a day of talks with both internal and external speakers to learn more about each others research interests and foster future collaboration between the groups.

XIV Encuentro Andaluz de Matemática Discreta, Universidad de Almería, January 22-24, 2025.
The Department of Mathematics of the University of Almeria, the research group TIC 146 Supercomputación-Algoritmos (SAL) and the Center for Development and Transfer of Mathematical Research to Industry (CDTIME), organize the XIV Andalusian Meeting of Discrete Mathematics, a space to bring together different research groups from Andalusia, Spain and the rest of the world working in the field of Discrete Mathematics.

2024

BGSMath Advanced Course: Threshold phenomena in random structures, Centre de Recerca Matemàtica - Universitat Politècnica de Catalunya, Barcelona, November 11-22, 2024.
The course will present the notion of threshold, a phenomenon consisting on a sudden behavioural change in the random structure produced by a small increase of the modelling parameter (temperature, energy, probability, … ). We will survey the most recent advances in the area as well as explore applications in other fields such as Sociology, Biology, Statistics and Computer Science. The last part of the course will be devoted to covering two very recent breakthroughs in the area: (1) the Kahn-Kalai conjecture, now Park-Pham theorem, asserting that thresholds can not differ too much from expected thresholds [10]. We plan to give a full proof of it; and (2) The satisfiability conjecture, now the Ding-Sly-Sun theorem, that pins down the thresh- old for a random k-SAT formula being satisfiable. The course is aimed at master and doctoral students, and at postdoctoral researchers in the areas of Mathematics, Computer Science and Physics, but is also open to all early career researchers and faculty in other areas that are interested in the fundamentals of threshold phenomena and its applications to different disciplines.

Interplays between Algebra, Combinatorics and Proof Formalization, Centre de Recerca Matemàtica, Barcelona, July 15 , 2024.
Exploratory workshop on popular formal logic systems used to formalize mathematical proofs, in the context of Algebra and Combinatorics. The workshop will explore the recent advances in between the areas, pionnered by June Huh. This is a collaborative initiative between the Centre de recherches mathématiques (CRM) in Montreal and the Centre de Recerca Matemàtica in Barcelona.

Combinatorial Designs and Codes (CODESCO’24), Sevilla, July 8-12, 2024.
The goal of the conference is to bring together researchers interested in combinatorial design theory, coding theory, graph theory, algebraic combinatorics and finite geometry, with particular emphasis on establishing new synergies among them, and new applications to other fields and to the real world, including artificial intelligence, communication networks, cryptography and machine learning. The conference is a satellite event of the 9th European Congress of Mathematics.

International Meeting on Numerical Semigroups 2024 (IMNS2024), Jerez de la Frontera, 8-12 July, 2024.
