We clarify the mathematical difficulty when for bosonic systems (i.e., unbounded operators) we rigorously construct a Liouville space, in which a Liouville operator acts, associated with a Hamiltonian, including unbounded and non-quasi-free cases. We give thermo field dynamics as an expression equiv
