Basing on results of Xu and Qin [10],and Guo [12] on cyclotomic elements in K2F for local fields F,we prove that every element in K2Q is a finite or infinite pr
This paper is joint with [27]. The authors prove in this article the existence and reveal its structure of uniform attractor for a two-dimensional nonautonomous
A type of complex systems under both random influence and memory effects is considered. The systems are modeled by a class of nonlinear stochastic delay-integro
We consider a discrete time risk model in which the net payout (insurance risk) {Xk,k=1,2,···} are assumed to take real values and belong to the
