Экстремально мультистабильнаясистема содержит бесконечное число сосуществующих аттракторов, определяющихся различными начальными условиями. Последнее обстоятельство вносит чрезвычайную неопределенность в ее поведение и открывает возможность использования такой системы, например, в криптографии и организации защищенной связи в системах коммуникаций. Поэтому особый интерес представляет понимание фундаментального принципа формирования экстремальной мультистабильности. Только поняв этот принцип, мы сможем генерировать системы с нужным поведением. Экстремальная мультистабильность многих известных в настоящее время систем может быть объяснена наличием феномена усиления смещения(offset boosting), предполагающего присутствие в системе параметра смещения. Как оказалось, отмена параметра смещения может привести к наличию в системе континуума сосуществующих аттракторов, которые непрерывно располагаются в фазовом пространстве, и простираются до бесконечности в определенном направлении. Это открытие может стать, например, объяснением возникновения и распространения торнадо и турбулентности. Внастоящей работе с использованием приема расширения размерности сконструированы две системы четвертого порядка без состояний равновесия, содержащие континуум сосуществующих скрытых хаотических аттракторов. Первая система построена на основе известной трехмерной системы Спротта, а вторая – на основе предложенной ранее авторами работы трехмерной системы, обладающей единственным скрытым хаотическим аттрактором размерности «почти 3». При этом вторая система содержит 2D решетку, представляющую собой объединение счетного числа полос, каждая из которых содержит континуум аттракторов.</p></abstract><trans-abstract xml:lang="en"><p>In recent years, many researchers have focused on studying the phenomenon of extreme multistability of dynamic systems. An extremely multistable system contains an infinite number of coexisting attractors determined by different initial conditions. The latter circumstance introduces extreme uncertainty into its behavior and opens up the possibility of using such a system, for example, in cryptography and the organization of secure communication ininformation transmission systems. Therefore, understanding the fundamental principle of the formation of extreme multistability is of particular interest. Only by understanding this principle we can generate systems with the desired behavior. Extreme multistability of many currently known systems can be explained by the presence of the phenomenon of offset boosting, which suggests the presence of an offset parameter in the system. As it turned out, the cancellationof the offset parameter can lead to the presence of a continuum of coexisting attractors in the system, which are continuously located in the phase space and extend to infinity in a certain direction. This discovery can become, for example, an explanation for the occurrenceand propagation of tornadoes and turbulence. In this paper, using the dimension expansion technique, two fourth-order systems without equilibrium states containing a continuum of coexisting hidden chaotic attractors are constructed. The first system is based on the wellknownthree-dimensional Sprott system, and the second is based on the three-dimensional system proposed earlier by the authors, which has a single hidden chaotic attractor of dimension “almost 3”. The second system contains a 2D lattice, which is a union of a countable number ofstrips, each of which contains a continuum of attractors.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>динамическая система</kwd><kwd>экстремальная мультистабильность</kwd><kwd>хаос</kwd><kwd>континуум сосуществующих аттракторов</kwd><kwd>показатели Ляпунова</kwd><kwd>размерность Каплана — Йорке.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>dynamic system</kwd><kwd>extreme multistability</kwd><kwd>chaos</kwd><kwd>continuum of coexisting attractors</kwd><kwd>Lyapunov exponents</kwd><kwd>Kaplan -– Yorke dimension.</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">Peng H., Ji’e M., Du X., Duan S., Wang L.
