Analysis of an economic model of Kaldor type modified with two discrete time delays
, 2018This article studies a continuous non linear economic dynamics with a delay of a Kaldor type modified in dimension two. The important results of this study are on the one hand, the boundedness of solutions, the existence of an attractive set, the ...

Stability and Unstability of the Standing Wave to Euler Equations
, 2017In this paper, we first discuss the well-posedness of linearizing equations, and then study the stability and unstability of the 3-D compressible Euler Equation, by analysing the existence of saddle point.

Kuramoto-Sivashinsky Equation and Free-interface Models in Combustion Theory
, 2016In combustion theory, a thin flame zone is usually replaced by a free interface. A very challenging problem is the derivation of a self-consistent equation for the flame front which yields a reduction of the dimensionality of the system.

Blow-Up of Solutions for a Singular Nonlocal Viscoelastic Equation
, 2011We study the nonlinear one-dimensional viscoelastic nonlocal problem: utt− 1 x (xux)x+ ∫ t 0 g(t−s) 1 x (xux(x,s))xds= |u| p−2u, with a nonlocal boundary condition.

Discrete Characterization of Exponential Stability of Evolution Family Over Hilbert Space
, 2014In this article we prove that if U = {U(m,n)}m≥n≥0 is a positive q-periodic discrete evolution family of bounded linear operators acting on a complex Hilbert space H then U is uniformly exponentially stable if for each unit vector x in H the series ∑∞ m ...
