    "abstract": "In this paper we reformulate free field theory models defined on the\nrectangular $D+1$ dimensional lattices as $D+1$ evolution models. This\nevolution is in part a simple linear evolution on free (``creation\u0027\u0027 and\n``annihilation\u0027\u0027) operators. Formal eigenvectors of this linear evolution can\nbe directly constructed, and them play the role of the ``physical\u0027\u0027 creation\nand annihilation operators. These operators being completed by a ``physical\u0027\u0027\nvacuum vector give the spectrum of the evolution operator, as well as the trace\nof the evolution operator give a correct expression for the partition function.\nAs an example, Bazhanov -- Baxter\u0027s free bosonic model is considered.",
