Ми вивчаємо ВКБ розвинення 2 × 2 системи лiнiйних диференцiальних рiвнянь з фуксовими сингулярностями. Основна увага сфокусована на генерувальнiй функцiї монодромного симплектоморфiзму, яка, вiдповiдно до недавньої роботи [10], є тiсно пов’язаною з тау-функцiєю Джимбо–Мiви. Ми обчислюємо першi три члени ВКБ розвинення генерувальної функцiї та встановлюємо її зв’язок з тау-функцiєю Бергмана.
