    "abstract": "We formulate a systematic algorithm for constructing a whole class of\nHermitian position-dependent-mass Hamiltonians which, to lowest order of\nperturbation theory, allow a description in terms of PT-symmetric Hamiltonians.\nThe method is applied to the Hermitian analogue of the PT-symmetric cubic\nanharmonic oscillator. A new example is provided by a Hamiltonian\n(approximately) equivalent to a PT-symmetric extension of the one-parameter\ntrigonometric Poschl-Teller potential.",
