The C operator in PT-symmetric quantum mechanics satisfies a system of three simultaneous algebraic operator equations, *C^2=1*, *[C,PT]=0*, and *[C,H]=0*. These equations are difficult to solve exactly, so perturbative methods have been used in the past to calculate C. The usual approach has been to express the Hamiltonian as $H=H_0+\epsilon...
