Alejandro Calleja (UCM-ICMAT) Configuration spaces of orbits and their app.n to character varieties

Configuration spaces of orbits and their application to character varieties Thursday 4th December 12h Room 117 & Youtube Channel The configuration space of orbits is a generalization of the well know configuration space of points but for algebraic varieties that are acted by some algebraic reductive group. The interesting fact about these spaces is that their geometry can be studied by relating it to the geometry of the usual configuration spaces of points. In this talk, we will use this approach to compute their E-polynomial in terms of the ones of the algebraic variety and of the algebraic group. We will also show how these spaces can be used to study character varieties of knots, focusing on the case of torus knots.
