The aim of this paper is to study the dynamical behavior non-autonomous stochastic lattice systems with Markovian switching. We first show existence an evolution system measures system. then pullback (or forward) asymptotic stability in distribution measures. finally prove that any limit point a tight sequence must be corresponding limiting as intensity noise converges zero. In particular, when...

In the framework of non-autonomous discrete dynamical systems in metric spaces, we propose new equilibrium points, called quasi-fixed and prove that they play a role similar to fixed points autonomous systems. this way some sufficient conditions for convergence iterative schemes type xk+1=Tkxk spaces are presented, where maps Tk contractivities with different points. The results include any reo...

After the Cold War, defense industries found themselves at a crossroads. However, it seems that they are gaining new momentum, as technologies such robotics and artificial intelligence enabling development of autonomous, highly innovative disruptive intelligent systems. Despite this impetus, there still doubts about where to invest limited financial resources boost high-tech industries. In orde...

in the present paper the linear oscillator in r3 with z =constanthas been considered. the aim is to determine the necessary conditions forthe persistence of periodic solutions under discontinuous perturbations. a newapproach based on a computational method has been used. at the end weapply our method on an example.
