Monthly group meetings
of the Advances in Applied Algebraic Geometry Group at KU Leuven
of the Advances in Applied Algebraic Geometry Group at KU Leuven
The A3G group at KU Leuven is led by Fatemeh Mohammadi.
The purpose of the monthly group meetings is to keep scientific exchange within the group lively and to discuss general organization issues coming up in the group.
Each meeting includes one to two informal presentations on current research, problematics that arise there, or suggestions for new projects.
The monthly group meetings are currently organized by Daniel Windisch.
For a list of the current and former group members, see here.
Dates and Presentations
04.02.2026, 14:30 - 16:00, Room Math 02.18
George Kenison: Reachability and Invariants for Linear Loops
Abstract: In this introductory talk, we will discuss computational problems related to linear loops (loops whose update assignments are all linear in the loop variables). These problems will come in several flavours such as, does a linear loop reach a specified target? and does the orbit of a linear loop stay within a permitted domain? We will give a broad overview of several open problems as well as their connections to problems in dynamical systems and algebraic geometry.
14.01.2026, 14:00 - 15:30, Room Math 02.18
Sebastian Seemann: Vandermonde cells and positive geometries
Abstract: We will define Vandermonde cells and provide 2 definitions of positive geometries. We will discuss examples and how Vandermonde cells fit into each framework.
03.12.2025, 14:00 - 15:30, Room Math 02.18
Sean Dewar: The Cayley-Menger variety and secant varieties
04.11.2025, 13:30 - 15:00, Room CS 05.128
Signe Lunqvist: Rigid realizations of graphs and scenes
