    "abstract": "To lowest order of perturbation theory we show that an equivalence can be\nestablished between a $\\cal PT$-symmetric generalized quartic anharmonic\noscillator model and a Hermitian position-dependent mass Hamiltonian $h$. An\nimportant feature of $h$ is that it reveals a domain of couplings where the\nquartic potential could be attractive, vanishing or repulsive. We also\ndetermine the associated physical quantities.",
