<正>In this paper,we analyze a three-dimensional differential system derived from the Chen system based on the first Lyapunov coefficient,and apply it to invest
The Lipschitz class Lip(K, α) on a local field K is defined in [10], and an equivalent relationship between the Ho¨lder type space Cα(K)[9] and Lip(K,α)
We consider the iterated function system { λz- 1, λz+ 1} in the complex plane, for λ in the open unit disk. Let M be the set of λ such that the attractor of
