From the introduction: In this paper, we define the Weyl CCR algebra and the resolvent CCR algebra and present some results in [D. Buchholz and H. Grundling, J. Funct. Anal. 254, No. 11, 2725–2779 (2008; Zbl 1148.46032)] in section 2. In section 3, we construct one-parameter groups of $$\ast$$-automorphisms on the resolvent CCR algebra. In section 4, we construct KMS states associated with one-parameter groups of $$\ast$$-automorphisms defined in the section 3 and present our main results [the author and T. Matsui, “KMS states of weakly coupled anharmonic crystals and the resolvent CCR algebra”, Preprint, arXiv:1601.04809]. In [“The resolvent algebra for oscillating lattice systems: dynamics, ground and equilibrium states”, Preprint, arXiv:1605.05259], D. Buchholz proved more general result. We explain some results of [Buchholz, loc. cit.] in section 5.
