Об асимптотике коэффициентов Лорана и ее применении в статистической механике

Abstract

В статье исследуется асимптотика коэффициентов ряда Лорана для мероморфных функций многих комплексных переменных. В основе исследования лежат понятия амебы для комплекс- ной гиперповерхности и логарифмического отображения Гаусса. Ряд Лорана интерпретируется как статистическая сумма, возникающая в квантовой термодинамике. Основной результат является обобщением на векторно-энергетический спектр известного метода Дарвина-Фаулера. Доказано, что если спектр конечен и порождает решетку, то для всех усредненных энергий, взятых из выпуклой оболочки спектра, средние значения распределений ансамбля совпадают с наиболее вероятными. Выдвигается гипотеза о верности этого утверждения и для бесконечного спектра.

We study asymptotics of the Laurent coefficients for meromorphic functions of several complex variables. We employ notions of complex hypersurface amoeba and logarithmic Gauss map. The main result of this note is the generalization of the Darwin-Fowler method for the vector energy spectrum case.
