Coloured graphical models
The paper "Coloured graphical models and their symmetries" by Isobel Davies and Orlando Marigliano has been recently published in the journal Le Matematiche!
Here is a link to the paper.
Abstract:
Coloured graphical models are Gaussian statistical models determined by an undirected coloured graph.These models can be described by linear spaces of symmetric matrices. We outline a relationship between the symmetries of the graph and the linear forms that vanish on the reciprocal variety of the model.In particular, we give four families for which such linear forms are completely described by symmetries.
Kick-off "Geometry at infinity"
In a few weeks, some members of our group will participate in the kick-off meeting of the 2nd phase of the Priority Programme "Geometry at Infinity" (SPP2026) of the German Research Foundation (DFG).
The SPP2026 funds many research groups across Germany (including us!) working on various subareas of geometry, topology, analysis and group theory.
See you there!
