Аннотация
В работе исследуется модель g-эссенции для лагранжиана вида L=R+2[aXn+eY-V(y/,y)]. Модели g-эссенции были предложены в последнее время в качестве альтернативы и как обобщение к-эссенции. Представлено 3 типа решений модели g-эссенции. Восстановлены соответствующие потенциалы и динамика скалярных и фермионных полей в соответствии с эволюцией масштабного фактора. Полученные результаты показывают, что модель g-эссенции может описывать фазы торможения и ускоренного расширения Вселенной.
