Sigmoidal approximations of a nonautonomous neural network with infinite delay and Heaviside function
Peter E. Kloeden, V. M. Villarragut
In this paper, we approximate a nonautonomous neural network with infinite delay and a Heaviside signal function by neural networks with sigmoidal signal functions. We show that th…
Exponential Ordering for Neutral Functional Differential Equations With Non-Autonomous Linear D-Operator
Rafael Obaya, Víctor M. Villarragut
We study neutral functional differential equations with stable linear non-autonomous -operator. The operator of convolution transforms into . We show that, if…
Attractors In Almost Periodic Nicholson Systems And Some Numerical Simulations
Ana M. Sanz, Víctor M. Villarragut
The existence of a global attractor is proved for the skew-product semiflow induced by almost periodic Nicholson systems and new conditions are given for the existence of a unique…
The exponential ordering for non-autonomous delay systems with applications to compartmental Nycholson systems
Sylvia Novo, Rafael Obaya, Ana M. Sanz +1
The exponential ordering is exploited in the context of non-auto\-no\-mous delay systems, inducing monotone skew-product semiflows under less restrictive conditions than usual. Som…
Asymptotic behavior of solutions of nonautonomous neutral dynamical systems
Sylvia Novo, Rafael Obaya, Victor M. Villarragut
This paper studies the dynamics of families of monotone nonautonomous neutral functional differential equations with nonautonomous operator, of great importance for their applicati…
