It leads to a parametric representation of partition function of an arbitrary macroscopic body, a possibility to describe a macroscopic body under excitation by a gas of some elementary quasiparticles etc. A phase transition is defined as such a state of a macroscopic body that its random variable is stable in sense of L\\'evy. From this definition it follows by deduction all general properties of phase transitions: existence of the renormalization semigroup, the singularity classification for thermodynamic functions, the phase transition universality and universality classes. On this basis we has also built a 2-parameter scaling theory of phase transitions, a thermodynamic function for the Ising model etc.", "revisions": [ { "version": "v1", "updated": "1997-03-03T16:49:50.000Z" } ], "analyses": { "keywords": [ "statistical mechanics", "foundations", "thermodynamic function", "arbitrary macroscopic body", "phase transition universality" ], "note": { "typesetting": "LaTeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable", "adsabs": "1997physics...3007B" } } }
