Tagungen und Workshops zum Thema Graphentheorie und Kombinatorik

ICERM

Braid groups and their generalizations play a central role in a number of places in 21st-century mathematics. In modern representation theory, braid groups have come to play an important organizing role, somewhat analogous to the role played by Weyl groups in classical representation theory. Recent advances have established strong connections between homological algebra (t-structures and stability conditions), geometric representation theory (Hilbert schemes, the Hecke category, and link homologies), and algebraic combinatorics (shuffle algebras, symmetric functions, and also Garside theory). Braid groups appear prominently in many of these connections. The goal of this workshop will be to bring experts in these different areas together to both communicate recent advances and also to formulate important questions for future work.

CONFERENCE

Institute of Mathematics and its Applications

Discrete mathematics is a branch of the mathematical sciences which poses a wide range of challenging research problems in its own right and gives rise to important applications in other fields. This 3rd IMA conference on discrete mathematics, following on from the previous two at Derby, will consider a range of aspects of discrete mathematics, both pure and applied. It is open to researchers working with mathematical structures and abstract constructs, and to those involved in the theory and practice of discrete mathematics. Results which establish links between different areas of discrete mathematics are welcomed, as are applications and the development of new tools. The purpose of this event is to highlight progress in the field through the development of novel theories, methodologies, and applications accordingly, and to inspire future work.

This is a subsequent meeting in the series of former Cracow Conferences on Graph Theory held in Niedzica (1990), Zgorzelisko (1994), Kazimierz Dolny (1997), Czorsztyn (2002), Ustroń (2006), Zgorzelisko (2010) and Rytro (2014, 2018). This event is also exceptional, as it shall provide opportunity to celebrate 70th birthday of Mariusz Woźniak.

Ergodic Schrödinger operators have been studied heavily since the 1970s, as they include many examples of physical interest, such as disordered media, electrons in an external magnetic field, and quasicrystals. These operators enjoy many subtle connections to other areas of mathematics, such as dynamical systems, topology, and group theory. The study of quantum graphs stems from the modeling of thin waveguides arranged into a topological network. Such models appeared already in the 1930s but have experienced a surge in popularity in recent years. Recent works have exploited connections between these two fields; these developments have scratched the surface of a much larger opportunity for collaboration. Thus, the aim of this workshop is to bring these two communities together for two purposes: to disseminate recent results, and to foster collaboration and communication between these communities.

The conference is devoted to the spectral theory and its applications in modern mathematical physics. There will be talks on the general operator theory, differential, integral and difference operators, scattering theory, inverse problems, periodic and ergodic operators, asymptotic methods and applications, e.g., on the modern quantum physics and nonlinear physics. We also plan to organize talks devoted to interesting general analytic problems.

The IPCO conference is under the auspices of the Mathematical Optimization Society and is held every year. The conference is a forum for researchers and practitioners working on various aspects of integer programming and combinatorial optimization. The aim is to present recent developments in theory, computation, and applications in these areas.

The topic of random graphs is at the forefront of applied probability, and it is one of the central topics in multidisciplinary science where mathematical ideas are used to model and understand the real world. At the same time, random graphs pose challenging mathematical problems that have attracted the attention from probabilists and combinatorialists since the 1960, with the pioneering work of Erdös and Rényi. Around the turn of the millennium, very large data sets started to become available, and several applied disciplines started to realize that many real-world networks, even though they are from various different origins, share many fascinating features. In particular, many of such networks are small worlds, meaning that graph distances in them are typically quite small, and they are scalefree, in the sense that there are enormous differences in the number of connections that their elements make. In particular, such networks are quite different from the classical random graph models, such as proposed by Erdös and Rényi. Spurred by these findings, many novel models have been introduced and properties have been investigated.

The Symmetries in Graphs, Maps, and Polytopes Workshop has been providing researchers interested in symmetries of discrete objects and structures to meet, share results, discuss open problems, and start new collaborations every four years since its inaugural meeting in 1998 in Flagstaff, Arizona. SIGMAP2022 will be held at the University of Alaska Fairbanks, and will provide an intimate setting for learning about recent developments in the study of symmetry of discrete geometric objects such as graphs, maps, polytopes, and maniplexes, discussing open problems in the area, and forming collaborations to tackle them.

The Young Researchers in Combinatorics workshop is aimed at PhD students and early-career academics working in Extremal and Probabilistic Combinatorics and related fields. By building an environment of mostly young researchers, we hope the participants will feel free to contribute their ideas openly, thus preparing them to undertake their own research projects. The workshop will consist mostly of working sessions in which participants collaborate on research problems, and a limited number of talks and lectures.
