Research Data in Discrete Mathematics
Max Planck Institute for Mathematics in the Sciences, Leipzig
Christiane Görgen, Martina Juhnke-Kubitzke, Thomas Kahle, Lars Kastner, Raman Sanyal, Christian Stump

Discrete mathematics has a long-standing tradition of generating and utilizing data to substantiate theories. Conversely, questions regarding the systematic generation of (counter-)examples drives research.

This 2-day “noon-to-noon” workshop is dedicated to the interplay of discrete data and discrete structures from a contemporary perspective. How FAIR is our data? How can modern technology help to analyze and interpret discrete data? Which connections to the sciences become visible through data? We approach these questions “hands-on” with invited lectures and panel discussions.

MaRDI Barcamp
Bielefeld, Germany
MaRDI (Tabea Krause, Victor Zimmermann) & Faculty of Mathematics, Bielefeld University (Claudia Köhler, Lukas Kühne)

Barcamp on research-data management in mathematics. The event will provide a forum to exchange expertise and questions in the field of mathematics-specific research-data management (RDM) and existing best practices. It is aimed at all researchers dealing with mathematical research data. In a Barcamp, the topics are decided on by the participants. This means that the focus will be very specific to the research questions and needs of the attendees. Questions could be: "What exactly does your community need?", "What works well and what doesn't?" or "How do young researchers or young projects implement 'good' RDM structures in the first place and what has proven successful?"

MaRDI 1-day-course on research data management.
Otto-von-Guericke Universität, Magdeburg
Christiane Görgen (Uni Leipzig), Jan Heiland (MPI Magdeburg), Thomas Kahle (OvGU Magdeburg), Tabea Krause (Uni Leipzig)

Every researcher in every research discipline has research data. Only, you may not call it data (yet).

To generate new math results, we build on previous results, perform own observations and thought experiments, try and fail many times until a proof is completed, find a little help from a colleague, and maybe use a computer to run a quick or complex computation. Isn’t all this just collecting data?

In this one-day course that was specifically designed for researchers in mathematics, we will learn and experience what mathematical research data is and how we can organize, document, and possibly publish it.


Oct 20, 2023 – Oct 20, 2023 20.10.23 – 20.10.23
MaRDI Barcamp on research data management
Otto-von-Guericke Universität, Magdeburg
Jan Heiland (MPI Magdeburg), Thomas Kahle (OvGU Magdeburg), Tabea Krause (Uni Leipzig)

The second MaRDI Barcamp on research-data management in mathematics hosted by the Mathematical Research Data Initiative (MaRDI) will take place on October 20th 2023 at the Otto-von-Guericke University of Magdeburg.

The event will provide a forum to exchange expertise and questions in the field of mathematics-specific research-data management and existing best practices. It is aimed at all researchers dealing with mathematical research data as well as at people from large mathematical research projects such as CRCs, priority programs or clusters of excellence.

What is a Barcamp? After short initial talks the topics are decided on by the participants. This means that the focus will be very specific to the research questions and needs of the attendees. Possible questions and topics we hope to address are: "What exactly does your community need?", "What works well and what doesn't?" or "How do young researchers or young projects implement 'good' RDM structures in the first place and what has proven successful?" We do not assume any prior knowledge with data management.

Combinatorial Coworkspace 2024
Haus Bergkranz, a guest house of the Goethe-Universität Frankfurt in Kleinwalsertal, Austria
Martina Juhnke, Thomas Kahle, Raman Sanyal, Christian Stump

A “coworkspace” is a place where people come together to work together or simply side-by-side. The goal of our “combinatorial coworkspace” is to give a group of motivated young and promising as well as established mathematicians such a place to explore new directions, applications, cooperations, and alliances within combinatorics and beyond. A context is provided by a suitable number of tutorials and lectures and the beautiful location encourages to take mathematical thoughts outdoors.

Lecture Series "Matroidal polynomials and their singularities"
Ruhr University Bochum, Germany
Gerhard Röhrle, Sven Wiesner

There will be a series of four talks by Uli Walther (Purdue University, USA) on (1) Matroids, matroidal polynomials, examples of these, including Kirchhoff polynomials, configuration polynomials, multivariable Tutte polynomials, matroid support polynomials. (2) Feynman diagrams and Feynman integrands (which are also matroidal). A discussion on torus actions on these hypersurfaces. The singular locus of certain matroidal polynomials: for configuration polynomials when the matroid is sufficiently connected, discuss irreducibility, size of singular locus, comparison between Jacobian ideal and a certain corank 2 determinantal ideal, Cohen-Macaulayness of these. The special case of the free resolution of the singular locus of the Kirchhoff polynomial of a complete graph. (3) For matroidal polynomials in general, it will be explained that they have rational singularities, and in the homogeneous case that they are F-regular. (4) Time permitting there will also be a discussion about the resolution of singularities.

CAP Days 2024
Université de Picardie Jules Verne, Amiens, France
Daniel Juteau (local organizer), Mohamed Barakat

CAP (shorthand for Categories, Algorithms, Programming) is a software project for algorithmic category theory written in GAP. It facilitates both the realization of specific instances of categories and the implementation of generic categorical algorithms.

The workshop is split into three kinds of activities:

  • Introductory talks about algorithmic category theory (ALCT), CAP as a dialect of ALCT, and CompilerForCAP.

  • An explicit live show-case implementation of a category constructor and an explicit categorical tower.

  • Exercise sessions implementing categorical algorithms in CAP. Participants are also invited to implement their own work in CAP and we will be happy to provide help.

The workshop aims at mathematicians, physicists, and computer scientists who want to learn about applications of algorithmic category theory and how CAP can be used to structure implementations in a categorical way.

Workshop "Wachspress Geometry"
University of Leipzig, Germany
Rainer Sinn, Martin Winter

The workshop "Wachspress Geometry" will take place on September 24 and 25, at the University of Leipzig.

Wachspress Geometry is a young subject that studies the so-called Wachspress objects, a family of closely related mathematical objects defined on convex polytopes that were found to arise in a surprising variety of contexts, including algebraic and convex geometry, polyhedral combinatorics, spectral graph theory, rigidity theory, statistics and Positive Geometry.

The workshop has the following goals:

  • to introduce Wachspress Geometry to a broad audience and to present its connection to Positive Geometry.

  • to bring together experts on the various aspects of Wachspress Geometry to explore the interactions between their perspectives.

  • to join them with experts on Positive Geometry to together develop the tools of Wachspress Geometry beyond convex polytopes.

Combinatorial Methods in Enumerative Algebra
ICTS Bengaluru, India
Angela Carnevale, Uri Onn, Amritanshu Prasad, Pooja Singla, Christopher Voll

Many algebraic counting problems give rise to integer sequences that hold information which is best accessed by encoding these numbers in appropriate generating functions. Numerous classical zeta and L-functions testify to this principle: Dirichlet’s zeta function enumerates ideals of a number field; Witten’s zeta function counts representations of Lie groups; Hasse– Weil zeta functions encode the numbers of rational points of algebraic varieties over finite fields. Analytic and arithmetic properties of these zeta functions hold or are expected to hold, the key to a treasure trove of information about the underlying structures. Zeta functions of groups and rings are invaluable tools in asymptotic group theory and ring theory. Often, they admit Euler product decompositions, with rational local factors that reflect regularity of structure in the underlying data.

We aim to bring together experts in the various relevant subject areas, including those in zeta functions of groups and rings and—crucially—in adjacent combinatorial areas, enabling them to address some of the outstanding problems in this field.

We will train young researchers to invite them to this vibrant area of enumerative algebra, give them the tools to both contribute to this area of asymptotic group and ring theory and relate it to their own area of expertise.


Dec 04, 2024 – Dec 06, 2024 04.12.24 – 06.12.24
Workshop "Geometry without Geometry"
Goethe University Frankfurt
Raman Sanyal, Martin Ulirsch

Matroids, M-convexity, and buildings are combinatorial abstractions of geometry that form the basis for the mindset of ``doing geometry without geometry''. Embracing this mindset has led to new perspectives for instance on volume polynomials and log-concavity (via Lorentzian polynomials), intersection theory (via combinatorial Chow rings), and flag manifolds (via flag matroids). The consequences are spectacular. This workshop aims at bringing together experts and aspiring experts from various areas of geometry and combinatorics to further explore the possibilities and implications of this approach.
