Assuming the ground state wavefunction, #,, , of a boson fluid is known, and writing the excited state wavefunctions in the form F/J,, , a linear eigenvalue equation of the form l?F = tPF is obtained, where E0 + E is the excited state energy, E0 is the ground state energy, and His a non-hermitian op
