    "abstract": "We show that partial dynamical symmetries (PDS) can occur at critical-points\nof quantum phase transitions, in which case, underlying competing symmetries\nare conserved exactly by a subset of states, and mix strongly in other states.\nSeveral types of PDS are demonstrated with the example of critical-point\nHamiltonians for first- and second-order transitions in the framework of the\ninteracting boson model, whose dynamical symmetries correspond to different\nshape-phases in nuclei.",
