Inaugural Colloquium – Topological, Computational & Algebraic Aspects of Complex Systems

2025-07-08T09:39:28+03:00July 7th, 2025|News, Topological, Computational, and Algebraic Aspects of Complex Systems|

The research group “Topological, Computational & Algebraic Aspects of Complex Systems” launches its 2025 activity with a one-day colloquium at the International Center for Mathematical Sciences – Sofia (ICMS). Three talks will highlight recent advances in birational geometry, tropical sandpiles, and quantum toric geometry.

Around combinatorial Viro’s patchworking, Geometry seminar talk by Arthur Renaudineau

2025-07-02T14:55:18+03:00July 2nd, 2025|Geometry Seminar|

This talk will be a survey on Viro’s combinatorial patchworking: a powerful method to construct real algebraic varieties. We will present the construction, give an idea of the proof, make the link with tropical geometry and then prove recent bounds on the Betti numbers of the real part. We will also see how the tropical perspective permits to generalize the initial construction.
