Название: An Order-by-Order Construction of Low-Temperature Phase Diagrams for Classical Lattice Systems
Автор: Tarnawski M.
Аннотация:
An inductive algorithm is presented for the construction of phase diagrams by means of the low-temperature expansion technique. First the phase diagram is studied in the set of formal series. In each step, properties of this phase diagram are related to extremal elements of some family of convex sets. Approximations of the phase diagram in order N are obtained by truncating all formal series at the Nth term
