Oscillation criteria for nonlinear differential equations with p ( t ) -Laplacian

Yutaka Shoukaku (2016)

Mathematica Bohemica

Recently there has been an increasing interest in studying p ( t ) -Laplacian equations, an example of which is given in the following form ( | u ' ( t ) | p ( t ) - 2 u ' ( t ) ) ' + c ( t ) | u ( t ) | q ( t ) - 2 u ( t ) = 0 , t > 0 . In particular, the first study of sufficient conditions for oscillatory solution of p ( t ) -Laplacian equations was made by Zhang (2007), but to our knowledge, there has not been a paper which gives the oscillatory conditions by utilizing Riccati inequality. Therefore, we establish sufficient conditions for oscillatory solution of nonlinear differential equations with...

Oscillation properties for parabolic equations of neutral type

Bao Tong Cui (1992)

Commentationes Mathematicae Universitatis Carolinae

The oscillation of the solutions of linear parabolic differential equations with deviating arguments are studied and sufficient conditions that all solutions of boundary value problems are oscillatory in a cylindrical domain are given.

Oscillations of higher order differential equations of neutral type

N. Parhi (2000)

Czechoslovak Mathematical Journal

In this paper, sufficient conditions have been obtained for oscillation of solutions of a class of n th order linear neutral delay-differential equations. Some of these results have been used to study oscillatory behaviour of solutions of a class of boundary value problems for neutral hyperbolic partial differential equations.

Oscillations of the solutions of nonlinear hyperbolic equations of neutral type.

D.P. Mishev, D.D. Bainov (1992)

Publicacions Matemàtiques

In this paper nonlinear hyperbolic equations of neutral type of a given form are considered, with certain boundary conditions. Under certain constraints on the coefficients of the equation and the boundary conditions, sufficient conditions for oscillation of the solutions of the problems considered are obtained.

Output feedback stabilization of a one-dimensional wave equation with an arbitrary time delay in boundary observation

Bao-Zhu Guo, Cheng-Zhong Xu, Hassan Hammouri (2012)

ESAIM: Control, Optimisation and Calculus of Variations

The stabilization with time delay in observation or control represents difficult mathematical challenges in the control of distributed parameter systems. It is well-known that the stability of closed-loop system achieved by some stabilizing output feedback laws may be destroyed by whatever small time delay there exists in observation. In this paper, we are concerned with a particularly interesting case: Boundary output feedback stabilization of a one-dimensional wave equation system for which the...
