Lyapunov exponents and poles in a non Hermitian dynamics
(Pergamon-Elsevier Science Ltd, 2017-06)
By means of expressing volumes in phase space in terms of traces of quantum operators, a relationship between the poles of the scattering matrix and the Lyapunov exponents in a non Hermitian quantum dynamics, is presented. ...
The Multilayer Control Scheme: a strategy to guide n-robots formations with obstacle avoidance
(Springer, 2015-06)
A multilayer scheme is here proposed to implement coordinated control of a group of mobile robots. Specifically, a trajectory tracking controller is proposed to coordinately guide a platoon of robots, with an obstacle ...
Dynamics characterization of modified Gross-Pitaevskii equation
(2013-07-15)
The dynamics of dissipative and coherent N-body systems, such as a Bose-Einstein condensate, which can be described by an extended Gross-Pitaevskii formalism, is investigated. In order to analyze chaotic and unstable ...
Central Lyapunov exponent of partially hyperbolic diffeomorphisms of ’T POT.3’
(American Mathematical Society - AMSProvidence, 2014-09)
In this paper we construct some "pathological'' volume preserving partially hyperbolic diffeomorphisms on 'T POT.3' such that their behavior in small scales in the central direction (Lyapunov exponent) is opposite to the ...
Nonsmooth Lyapunov pairs for differential inclusions governed by operators with nonempty interior domain
(Springer, 2016)
The general theory of Lyapunov stability of first-order differential inclusions in Hilbert spaces has been studied by the authors in the previous paper (Adly et al. in Nonlinear Anal 75(3): 985-1008, 2012). This new ...
Lyapunov theorems for measure functional differential equations via Kurzweil-equations
(Wiley-VCH Verlag GmbHWeinheim, 2015)
We consider measure functional differential equations (we write measure FDEs) of the form Dx = f ('X IND. T', t)Dg, where f is Perron–Stieltjes integrable, 'X IND. T' is given by 'X IND. T'(θ) = x(t + θ), θ ∈ [−r, 0], with ...
A necessary and sufficient condition for the stability of interval difference equation via interval Lyapunov equation
(2022-01-01)
Interval difference equations can be used for modeling biological, economic, or physical systems that, due to lack of information or measurement errors in the input data from real-world applications, contain uncertainties. ...

A note on the asymptotic stability
(Scitech research organisation, 2015-12)
In this paper, we stude the influence of the perturbing term in equation x’ = f(t, x) + g(t, x), on the asymptotically behavior of x’ = f(t, x).
