Abstract:The construction of relation gl(n)-modules has a combinatorial flavor, and has as main advantage the explicitness of the algebra action. The correspondence between relation modules and certain directed graphs allow us to get structural information about the modules via an action of the symmetric group on the corresponding graphs. In this talk I relate the orbits of such action with realizations of a highest weight module with respect to different Gelfand-Tsetlin subalgebras.
