Tagungen und Workshops zum Thema Graphentheorie und Kombinatorik

Casa Matemática Oaxaca (CMO)

These are a series of combinatorial workshops, held once per semester, each on a Saturday. The series began with its first meeting in spring 2010. They rotate among the universities in and around the Research Triangle. Participants come from numerous colleges and universities within a few hours drive, and some from even farther away. These workshops are funded by the National Science Foundation, in particular enabling us to bring in four exciting speakers to give one hour talks each time as well as funding travel expenses for participants.

Graph Theory has grown into a major area of Discrete Mathematics with applications in a wide variety of fields: Computer Science, Coding Theory, Cryptography, Electrical Engineering, Sociology, Psychology, Physics, Chemistry, Economics, etc. It also provides a premier interdisciplinary platform for researchers to present and discuss the most recent innovations as well as practical challenges encountered in the field of Graph Theory. In the proposed conference, we have planned to conduct a symposium on graph decompositions. Graph decompositions have a wide variety of applications such as computer architecture, designing reliable communication networks. Hypercubes, Butterfly network, and de Bruijn network are proved to be good interconnection networks.

Algebraic Combinatorics has recently been energized through inAAC2020_imageteractions with Probability, Mathematical Physics, and Theoretical Computer Science. Of great interest is how classical algebro-combinatorial objects behave when their defining parameters become large or random. This new perspective has birthed the rapidly developing subject of Asymptotic Algebraic Combinatorics, the subject of this workshop.

This workshop, sponsored by AIM and the NSF, will be devoted to the topology of configuration spaces of graphs.

Combinatorics is a branch of mathematics concerning the study of finite or countable discrete structures. It finds applications in various domains. In particular, due to advances in biotechnology, applications in biology and medical research have increased, many of which arose from the study of bio-molecular sequences and their interaction. This program aims to investigate the combinatorial problems in strings and graphs and their applications in biological science, hoping to explore new ideas and techniques in analyzing these big datasets.

The new and rapidly expanding area of Analytic Combinatorics in Several Variables (ACSV) concerns enumeration problems in such areas as lattice walks, statistical mechanical models, quantum walks and other exactly solvable models where asymptotic estimation of coefficients of a bivariate or multivariate generating function is required. The multivariate setting incorporates a wider swath of mathematics. including singularity theory, algebraic topology, and computational algebra. Participants in this MRC will be introduced to problems from these areas of mathematics whose solutions have direct applications to ACSV. These problems are not hard to state in the language of disciplines such as Morse theory, harmonic analysis, or commutative algebra, but they ask questions not typical in those fields. A long-term goal is to advance and automate this work, so that its benefits can be used by other researchers in mathematics and the natural sciences through implementations in computer algebra packages. Problems for this MRC will be arranged around five central topics: effective computer algebra methods, algorithms using computational topology, multivariate asymptotic phase transitions, singular transforms for degenerate saddle-point integrals, and applications of harmonic analysis and singularity theory. Researchers with knowledge in any one of these areas are encouraged to apply to this MRC.

The Cologne-Twente Workshop on Graphs and Combinatorial Optimization 2020 welcomes contributions on theory and applications of discrete algorithms, graphs and combinatorial optimization in the wider sense. The series of Cologne-Twente Workshops on Graphs and Combinatorial Optimization started with meetings organized every two years by the universities of Cologne and Twente. The organizational base was later expanded by other universities. Since 2003 the workshop is held (almost) every year.

Andrew Ranicki and his theory of algebraic surgery played a central role in linking manifold theory, algebraic K-theory, and its close cousin L-theory. These areas have seen great developments and advances in the last decade from distinct research communities. This workshop will bring together mathematicians working on the topology of high-dimensional manifolds and their automorphisms with those working on the algebraic K-theory (and its cousins hermitian K-theory and L-theory) of rings and ring spectra, in order to share recent progress in these areas and kindle a fresh interaction between them.

At the conference we will be celebrating the 65th birthday of Paul Terwilliger. As such, the general theme of this conference will be the mathematical topics that Paul has worked on over the years (which all have relationships to the q-Onsager algebra).

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 without senior researchers, we hope the participants will feel free to contribute their ideas openly, thus preparing them to undertake their own research projects. The workshop consists mostly of working sessions in which participants collaborate on research problems, and a limited number of talks and lectures. We aim to host around 10 invited participants and about 25 PhD students for a week between 19 and 25 July 2020 at ICMS Edinburgh. Accommodation and refreshments are provided for all participants, as well as a conference dinner. A registration fee of 100GBP is payable by all non-invited participants. We expect to start accepting applications in October 2019.

This workshop, sponsored by AIM and the NSF, is devoted to the Albertson conjecture and other problems related to crossing numbers. The crossing number of a graph is the minimum number of edge crossings in a drawing of the graph in the plane. Determining or estimating the crossing number of a graph is one of the oldest problems in graph theory.
