Title: Partition function step-by-step integration without approximations. One-dimensional ferromagnet with long-range potential
Authors: Yu.V. Kozitsky

One-dimensional Ising-like ferromagnetic model with a pair spin-spin interaction decaying as (dist)$^{-1-\lambda}$ is considered. For this model the step-by-step integration procedure in the spirit of I.R.Yukhnovskii [1] is developed. Its main feature is the absence of any approximations.
