RésumeIn this talk I will describe a procedure, based on constrained or relative critical loci, that allows to construct lagrangian subvarieties inside symplectic quiver varieties. We will see how this works on the example of the Hilbert scheme of points on the plane. I will explain using derived geometry that the noncommutative counterpart of lagrangian structures is given by so-called relative Calabi--Yau ones, involving for instance generalizations of Ginzburg dg-algebras. If time permits I will give applications to multiplicative variants linked to Poisson and Hamiltonian geometries. This is a joint work with Damien Calaque and Sarah Scherotzke.
