چکیده

We establish some oscillation criteria for the solutions to forced higher-order differential equations. We do not assume that the forcing term is the n-th derivative of an oscillatory function, and do not assume that the coefficients are of a definite sign. Our results are illustrated with examples.

Oscillation Criteria for Forced Second-Order Functional Dynamic Equations with Mixed Nonlinearities on Time Scales

We are concerned with the oscillation of certain forced second-order functional dynamic equation with mixed nonlinearities. Our results in a particular case solve a problem posed by Anderson, and our results in the special cases when the time scale is the set of real numbers and the set of integers involve and improve some oscillation results for second-order differential and difference equatio...

Forced Oscillation of Second-order Nonlinear Dynamic Equations on Time Scales

In this paper, by defining a class of functions, we establish some oscillation criteria for the second order nonlinear dynamic equations with forced term x (t) + a(t)f(x(q(t))) = e(t) on a time scale T. Our results unify the oscillation of the second order forced differential equation and the second order forced difference equation. An example is considered to illustrate the main results.

Forced oscillation of higher-order nonlinear differential equations

Some new criteria have been established for the oscillation of higher-order forced nonlinear differential equation of the form Lnx(t) + q(t)F(x(t)) = e(t) according to the smart choice of a class of new auxiliary functions. No restriction is imposed on the forcing term e(t) as those assumed in [A.G. Kartsatos, Maintenance of oscillations under the effect of a periodic forcing term, Proc. Amer. ...
