Аннотация
В статье рассматривается тензорная сумма двух моделей Фридрихса с возмущением второго ранга. Гамильтониану соответствует система трех квантовых частиц на одномерной решетке. Исследуется количество и расположение собственных значений. Существование собственных значений, расположенных, соответственно, внутри, в зазоре и ниже дна существенного спектра доказано.
