Название: The Onsager Formula, the Fisher-Hartwig Conjecture, and Their Influence on Research into Toeplitz Operators
Автор: Bottcher A.
This is not primarily a paper about applications of mathematics to statistical physics, but rather a report on how a particular problem of statistical physics has resulted in an extensive mathematical theory. The problem alluded to is the computation of the spontaneous magnetization Mo(T) of the two-dimensional Ising model with nearest-neighbor interactions, whose solution for temperatures T below the Curie point Tc was given by the famous formula of Lars Onsager in 1948. The theory grown out of this formula is the edifice of Toeplitz determinants, matrices, and operators.
