Asymptotics for solutions of periodic difference systems
(2009)
Using dichotomies and periodic conditions, we obtain asymptotic formulas for solutions of a difference system of Poincaré type with periodic coefficients. Some results about the theory of existence of periodic solutions ...
Asymptotic to systems with memory and non-local initial data
(World Scientific Publishing, 2020)
We study the existence and the asymptotic behavior of the solution of an abstract viscoelastic system submitted to non-local initial data. u(tt )+ Au - integral(t)(0) g(t - s)Bu(s)ds = 0 u(0) = xi(u) in V, u(t) (0) = eta(u) ...
On the behavior of positive solutions of semilinear elliptic equations in asymptotically cylindrical domains
(Birkhauser Verlag, 2017)
The goal of this note is to study the asymptotic behavior of positive solutions for a class of semilinear elliptic equations which can be realized as minimizers of their energy functionals. This class includes the Fisher-KPP ...
The Fate of the Landau Levels under Perturbations of Constant Sign
(OXFORD UNIV PRESS, 2009)
We show that the Landau levels cease to be eigenvalues if we perturb the 2D Schrodinger operator with a constant magnetic field, by bounded electric potentials of fixed sign. We also show that, if the perturbation is not ...
Asymptotic Skewness in Exponential Family Nonlinear Models
(TAYLOR & FRANCIS INC, 2009)
In this article, we give an asymptotic formula of order n(-1/2), where n is the sample size, for the skewness of the distributions of the maximum likelihood estimates of the parameters in exponencial family nonlinear models. ...
Asymptotic behaviour of solutions to linear neutral delay differential equations with periodic coefficients
(American Institute of Mathematical SciencesSpringfield, 2014-05)
We study the asymptotic behaviour of the solutions of a class of
linear neutral delay differential equations with discrete delay where the coeffi-
cients of the non neutral part are periodic functions which are rational ...
A sign-changing solution for an asymptotically linear Schrödinger equation
(Cambridge University PressNew York, 2015-10)
The aim of this paper is to present a sign-changing solution for a class of radially symmetric asymptotically linear Schrödinger equations. The proof is variational and the Ekeland variational principle is employed as well ...
