| Research Abstract |
In this research, we have studied KMS states and phase transitions in quantum lattice systems, using the theory of unbounded derivations various results on KMS states obtained in the head investigator's book of "Operator algebras in dynamical systems" have been deepen by this research. The main results in this research have been published in the papers of "KMS states and phase transitions, I,II" by the head investigator.
