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.

The summer school will give a self-contained introduction aimed at beginning graduate students, and introduce participants to the latest developments. In addition to attending the lectures, students will meet in intensive problem and discussion sessions that will explore and extend the topics developed in the lectures.

There will be an EMS (European Mathematical Society) summer school on Combinatorial Commutative Algebra at Gebze Technical University (in Turkey) on August 8-12, 2022. The summer school is part of a larger event acronymed SCALE (Symbolic Computation: Algorithms, Learning, and Engineering). The main goal of this summer school is to create an environment for participants, especially for postdocs and graduate students, to learn about some of the foundational topics and emerging research directions in combinatorial commutative algebra. Three courses will be offered by the invited speakers (Jürgen Herzog, Takayuki Hibi, Sara Saeedi Madani) and the participants will be given the opportunity to present short talks or posters. There will be support for accommodation and travel costs of students and early stage researchers. If you wish to apply for support, please submit your application by May 15, 2022. Please visit the webpage https://scale.gtu.edu.tr/CCA.html for more details including registration and funding application links.

Enumerative combinatorics is a dynamic subfield of the mathematical sciences with many challenging research problems, ingenious and sophisticated techniques, and important applications in various scientific fields. Questions from a broad range of areas, including algebra, topology, probability, computer science, physical, chemical and biological sciences, have some surprising hidden combinatorial structures that require enumerative methods for their solution.

The conference will be devoted to all areas of graph theory and related topics. During the conference, which will be held in person, we will have several special events. In particular, we will use the opportunity to celebrate 60th birthday of Sandi Klavžar.

Graph Drawing is concerned with the geometric representation of graphs and constitutes the algorithmic core of Network Visualization. Graph Drawing and Network Visualization are motivated by applications where it is crucial to visually analyze and interact with relational datasets. Examples of such application areas include data science, social sciences, web computing, information systems, biology, geography, business intelligence, information security, or software engineering. GD has been the main annual event in this area for about 30 years. Its focus is on combinatorial and algorithmic aspects of graph drawing, as well as the design of network visualization systems and interfaces. Researchers and practitioners working on any aspects of graph drawing and network visualization are invited to contribute papers and posters and to participate in the symposium and the graph drawing contest.

Diagrams is the only conference series that provides a united forum for all areas that are concerned with the study of diagrams and has a multidisciplinary emphasis. Diagrams 2022 is the thirteenth conference in the series that started in 2000. The multidisciplinary nature of Diagrams means it encompasses: architecture, art, artificial intelligence, biology, cartography, cognitive science, computer science, education, graphic design, history of science, human-computer interaction, linguistics, logic, mathematics, philosophy, psychology, and software modelling. The conference attracts a large number of researchers from these interrelated fields, positioning Diagrams as the major international event in the area.

The scope of the conference is intended to cover most aspects of modern combinatorics, including graph theory, probabilistic combinatorics, extremal combinatorics, combinatorial optimization, algorithmic problems, combinatorial number theory, applications of combinatorics in computer science.

The study of Lefschetz properties for Artinian algebras was motivated by the Lefschetz theory for projective manifolds, begun by S. Lefschetz, and well established by the late 1950's. Many of the important Artinian graded algebras appear as cohomology rings of an algebraic variety or manifold, though recent important developments have demonstrated important cases of the Lefschetz properties beyond such geometric settings (such as Coxeter groups or matroids). This renews interest in understanding the Lefschetz property, and Artinian algebras that admit them, systematically.
