| Abstract | In the paper, we present a new stability theory of fractional dynamics, i.e., the stability for manifolds of equilibrium state of a fractional Birkhoffian system, in terms of Riesz derivatives, and explore its applications. For an autonomous fractional Birkhoffian system, the gradient representation and second-order gradient representation are studied, and the conditions under which the system can be considered as a gradient system and a second-order gradient system are given, respectively. Then, equilibrium equations, perturbation equations and first approximate equations are obtained, and the stability theorem for manifolds of equilibrium state of the general autonomous system is used to a fractional Birkhoffian system, and three criterions on the stability for manifolds of the equilibrium state of the system are investigated. As special cases of the fractional Birkhoffian method, the three criterions can also be applied to a traditional Birkhoffian system, a fractional Hamiltonian system and a classical Hamiltonian system, respectively. As applications, by using the fractional Birkhoffian method of this paper, we construct three kinds of fractional dynamical models, which include a four-dimensional fractional dynamical model, a fractional Hénon–Heiles model and a fractional Lorentz–Dirac model, and we explore the stability for manifolds of the equilibrium state of these models, respectively. This work provides a general method for studying the dynamic stability of an actual fractional dynamical model that is related to science and engineering. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
