Исследуется операторная конструкция предложенная О.И. Богоявленским, и имеющая аттракторы в фазовом пространстве. Для вывода нового нелинейного уравнения используется операторная структура Li = [L,A] + P(L), расширяющая конструкцию Лакса, с L,A - дифференциальными операторами, P(L) - полином 1-го порядка. В качестве оператора L рассматривается дифференциальный оператор Дирака первого рода. Определяются необходимые и достаточные условия, при которых операторное уравнение является условием совместности трех линейных дифференциальных уравнений: первое - является уравнением на собственные значения оператора L по пространственной переменной и спектральными значениями, параметрически зависящими от времени, второе - описывает динамику собственных функций оператора L по временной переменной, третье - определяет спектральную функцию. Показано, что спектральная функция может иметь орбиту - устойчивое подмногообразие или аттрактор.</p></abstract><trans-abstract xml:lang="en"><p>Theory of integrable nonlinear equations possessing soliton solutions of a new type - tipper solitons. The operator examines the design proposed by O.I. Bogoyavlensky, and having attractors in the phase space. For output of a new nonlinear equation is used operator structure Li = [L,A] + P(L), that extends the design of lax, L,A - differential operators, P(L) - polynomial 1-th order. As the operator L, one considers the dierential Dirac operator of the first kind. Are defined by necessary and sufficient conditions under which the operator equation is the compatibility condition for the three linear differential equations: the irst is the eigenvalue equation of the operator L on the space variables and the spectral values parametrically dependent on time, the second describes the dynamics of the eigenfunctions of the operator L in a temporary variable, and the third one deines the spectral function. It is shown that the spectral function can have an orbit -stable subvariety or attractor.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>аттрактор</kwd><kwd>нелинейное уравнение в частных производных</kwd><kwd>оператор Дирака</kwd><kwd>спектральная функция</kwd><kwd>операторное уравнение</kwd><kwd>комплексная функция</kwd><kwd>полином</kwd><kwd>attractor</kwd><kwd>nonlinear partial differential equation</kwd><kwd>Dirac operator</kwd><kwd>spectral function</kwd><kwd>operator equation</kwd><kwd>complex function</kwd><kwd>polynomial</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Богоявленский О.И.
