<font size="+1"><b>Бездисперсионные интегрируемые системы и
уравнения Богомольного на фоне геометрии Эйнштейна-Вейля</b></font><br>
<br>
<div class="abstract tex">
Получена бездисперсионная интегрируемая система, описывающая
локальную форму общей трехмерной геометрии Эйнштейна–Вейля с
евклидовой (положительной) сигнатурой, сконструировано ее
матричное расширение и показано, что оно приводит к уравнениям
Богомольного для неабелева монополя на фоне геометрии
Эйнштейна–Вейля. Рассматривается также соответствующая
бездисперсионная интегрируемая иерархия, ее матричное расширение и
схема одевания.

<font size="+1"><b>Неустойчивые моды линеаризации НУШ вблизи бризера
Ахмедиева</b></font><br>
<br>
<div class="abstract tex">
В литературе содержится утверждение о стабильности бризера
Ахмедиева за счет механизма "насыщения нелинейности". В качестве
аргумента используется тот факт, что среди квадратов волновых
функций, по которым разлагаются решения линераизованной задачи,
нет растущих по времени. Нами показано, что эта аргументация
ошибочна, поскольку из-за наличия двойной точки в спектральной
задаче в разложение по квадаратам собственных фукций также входят
производные по спектральному параметру. Мы явно предъявляем
"упущенные моды".
