Аннотация:
Пространственные и временные температурные корреляционные функции в XXO-цепочке Гейзенберга (в поперечном магнитном поле) выражены в терминах детерминанта Фредгольма линейных интегральных операторов. Это сделано для оценки асимптотического поведения этих корреляционных функций, которая будет представлена в следующей работе.
