, 2012 In this paper we study the continuity of invariant sets for nonautonomous infinite-dimensional dynamical systems under singular perturbations. We extend the existing results on lower-semicontinuity of attractors of autonomous and nonautonomous dynamical ...

The Gesture as an Autonomous Nonlinear Dynamical System
, 2016 We propose a theory of how the speech gesture determines change in a functionally relevant variable of vocal tract state (e.g., constriction degree).

A new SSI algorithm for LPTV systems: Application to a hinged-bladed helicopter [PDF]
, 2014 Many systems such as turbo-generators, wind turbines and helicopters show intrinsic time-periodic behaviors. Usually, these structures are considered to be faithfully modeled as linear time-invariant (LTI).

Nonautonomous chemostats with variable delays [PDF]
, 2015 The appearance of delay terms in a chemostat model can be fully justified since the future behavior of a dynamical system does not in general depend only on the present but also on its history.

Upper semicontinuity of attractors of non-autonomous dynamical systems for small perturbations
Electronic Journal of Differential Equations, 2002 We study the problem of upper semicontinuity of compact global attractors of non-autonomous dynamical systems for small perturbations. For the general nonautonomous dynamical systems, we give the conditions of upper semicontinuity of attractors for small

Heteroclinic points of multi-dimensional dynamical systems
Electronic Journal of Differential Equations, 2003 The authors investigate dynamical behavior of multi-dimensional dynamical systems. These are the systems with a multi-dimensional independent ``time" variable.

Attractors for a second order nonautonomous lattice dynamical system with nonlinear damping
, 2007 In this Letter, the existence of compact pullback attractors is considered for a second order nonautonomous lattice dynamical system with nonlinear damping arising from spatial discretization of wave equations in R k .

On nonautonomous discrete dynamical systems driven by means
Advances in Difference Equations, 2006 We investigate the asymptotic behavior of nonautonomous discrete dynamical systems governed by the system of difference equations (recursive equations): yj(n+1) = Fj(n,y,(n)); j = 1,...,k, n = 0,1,2,..., where y(n) = (y1(n),...,yk(n)) ∈ ℝk ...

Nonautonomous Differential Systems in Two Dimensions
, 2008 This contribution is divided into three parts: in the first one, we study minimal subsets of the projective flow defined by a two-dimensional dynamical system. In the second part, we discuss some recent developments in the spectral theory and inverse

, 1997 The exact solution and the invariant Cartan operator of the linear nonautonomous system with su(1,1)$\oplus$h(3) dynamical algebra are obtained by using the method of algebraic dynamics. A novel, indirect quantum-classical correspondence of the solutions
