Quantum graphs are a useful model in microelectronics and other areas.In this talk we report a solution [1] to a longstanding open problem showing that any self-adjoint coupling in the graph vertices allowed by probability current conservation can by approximated by a suitable family of scaled Schrödinger operators on a "fat graph",in other words,a network of tubes whose widths shrink to zero.
