|Abstract:||The Hilbert space in PT -symmetric quantum mechanics is formulated as a linear vector space with a dynamic inner product. The most general PT - symmetric matrix Hamiltonians are constructed for the 2 × 2 and 3 × 3 cases. In the former case, the PT -symmetric Hamiltonian represents the most general matrix Hamiltonian with a real spectrum. In both cases, Hermitian matrices are shown to be special cases of PT -symmetric matrices. This finding confirms and strengthens the early belief that the PT -symmetric quantum mechanics is a generalization of the conventional Hermitian quantum mechanics. © 2010 IOP Publishing Ltd.|
