چکیده
Two-sided quantum K-systems can be considered on the C* and von Neumann level. Via rst and second quantization examples can be constructed without obstacles on the C* level. On the von Neumann level, however, q-deformation in second quantization prohibits KMS-states. Nevertheless, an example can be found of a two-sided modular K-system, where the relative commutants are trivial.
