In this paper, we discuss the existence of positive solutions for a nonlinear fractional q-difference equations boundary value problem {(Dαq)(t) + a(t)f(u(t))=0, 0<t<1, u(0) = (Dqu)(0) = 0, (Dqu)(1) = βu(η), where 0 < q < 1, 2 < α ≤ 3, 0 < η < 1, 0 < βηα-1 < [α-1], by applying a fixed point theorem on cone. At last, we give an example to illuminate the results by computation.
In this paper, the global robust asymptotic stability problem is considered for stochastic cellular neural networks with time delays and parameter uncertainties. The aim of this paper is to establish easily verifiable conditions under which the stochastic cellular neural networks is globally robustly asymptotically stable in the mean square for all admissible parameter uncertainties. Base on Lyapunov-...
