Аннотация:
В данной работе изучаются вопросы, связанные с прямыми изоклинами автономной
дифференциальной системы, правая часть которой представляет собой полином
третьей степени. Для этой системы, имеющей максимальное число параллельных
между собой прямых изоклин, дана оценка сверху общего числа прямых изоклин.
Кроме этого дана оценка сверху числа инвариантных прямых кубической системы,
имеющей хотя бы одно состояние равновесия и пять параллельных между собой прямых
изоклин. Рассмотрены достаточные условия отсутствия предельных циклов
у системы, имеющей три инвариантные прямые и максимальное число параллельных
между собой прямых изоклин.
