Resumen:Moment graphs appear naturally in the representation theory of Lie algebras, the theory of Coxeter groups and the geometry of certain algebraic varieties equipped with an action of a torus. I will discuss the case in which the graphs arising from different settings coincide, witnessing the interplay of representation theory, geometry and algebraic combinatorics.
