Birdtracks 2025
The birdtracks method allows for a concise and transparent way of calculating with tensors, with applications that reach across QCD, general relativity, differential geometry, lattice field theory, and representation theory. The aim of this meeting is to bring together experts from different fields, who will explain in which context they use birdtracks, why they use them, and what the special features, advantages, and disadvantages are in their particular context. In this way, the meeting will allow exchange, progress, and synergy across different fields of research.
This meeting will take place online over Zoom during the afternoons (CET) March 10-12 and will be open to registered participants free of charge. The opening talk 2025 will be given by Stéphane Peigné.
Confirmed speakers include:
- Bakar Chargeishvili (Karlsruhe Institute of Technology)
Generating orthogonal multiplet bases in SU(Nc ) color space using SMT solvers - Jae Goode (University of Edinburgh)
Enhancing tensor reduction with index symmetry - Greg Jackson (SUBATECH, Université de Nantes)
Color transitions from medium-induced coherent gluon radiation - Thorsten Ohl (Universität Würzburg)
Birdtracks of exotic SU(N ) color structures - Stéphane Peigné (SUBATECH, Université de Nantes)
A very elementary introduction to birdtracks for SU(N ) - Bernanda Telalovic (Niels Bohr Institute, University of Copenhagen)
Keeping track of N when decomposing tensor products of SU(N ) irreps
The meeting is jointly organized by Stefan Keppeler (Universität Tübingen, stefan.keppeler@uni-tuebingen.de), Simon Plätzer (Universität Graz and Universität Wien, simon.plaetzer@uni-graz.at) and Malin Sjödahl (Lund University, malin.sjodahl@fysik.lu.se).
