We introduce a novel approach utilizing techniques from noncommutative Poisson geometry to study the algebra of invariants of two
n×n matrices. We completely resolve the open problem of computing the algebra of invariants for two
4×4 matrices. As an application, we derive a complete description of the invariant commuting variety of
4×4 matrices and the fourth Calogero-Moser space. This is joint work with X. García-Martínez and R. Turdibaev.
Professor Farkhod Eshmatov is the Director of the Department of Mathematics at New Uzbekistan University. His research focuses on noncommutative algebraic geometry and mathematical physics.
