Уважаемые коллеги!

На заседании Ученого совета в пятницу  3 февраля в 11:30 будут заслушаны
2 доклада:

1) _А. Артемьев_, В.Белавин
*Одноточечные корреляционные числа на торе в минимальной Лиувиллевской
гравитации*

Предложен метод вычисления "из первых принципов" одноточечных
корреляционных чисел в (2,2p+1) минимальной Лиувиллевской гравитации на
торе. Метод основан на "высших уравнений движения" Ал. Замолодчикова в
теории Лиувилля, ранее успешно применённых к вычислению корреляторов на
сфере. Показано, что этот подход позволяет свести входящие в определение
корреляторов интегралов по пространствам модулей к явно вычислимым
граничным вкладам. Результаты согласуются с подходом матричных моделей.
Доклад основан на работе arXiv: 2210.14568.

2) Е.А. Кочурин, _Е.А. Кузнецов_
*Прямое численное моделирование акустической турбулентности: спектр
Захарова-Сагдеева* (короткий доклад)

Проведено прямое численное моделирование трехмерной акустической
турбулентности в среде со слабой положительной дисперсией. Показано, что
в начале длинноволновой области в распределении энергии в k-пространстве
происходит формирование джетов в виде узких конусов. При больших
волновых числах конусы уширяются, а распределение соответственно
стремится к изотропному. В этой области волновых чисел усредненный по
углу спектр турбулентности приобретает степенной характер с показателем,
близким к -2/3, что соответствует спектру слабой акустической
турбулентности Захарова-Сагдеева.

ID и пароль онлайн-трансляций в Zoom те же, что и для предыдущих
трансляций докладов на Ученом совете:
