Popis:	In the context of non-Hermitian but PT-symmetric Hamiltonians, we explore the systematics of the coefficients of the multiple commutators that appear in the perturbative expansions for Q, the exponent of the metric operator, and h, the equivalent Hermitian Hamiltonian. We find exact expressions for both Q and h for PT-symmetric versions of the dual two-dimensional quantum field theories, the sine-Gordon model and the massive Thirring model, and elucidate how these solutions arise from the structure of the multiple commutator coefficients.
