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...

Interval Oscillation Criteria for Second Order Mixed Nonlinear Forced Impulsive Differential Equation with Damping Term

In this paper, interval oscillation criteria are established for second order forced impulsive differential equations with mixed nonlinearities of the form ⎧⎪⎨ ⎪⎩ ( r(t)Φα(x′(t)) )′ + p(t)Φα(x′(t))+q(t)Φα(x(t))+ n ∑ i=1 qi(t)Φβi (x(t)) = e(t), t = τk, x(τk) = akx(τk), x′(τk+) = bkx′(τk), k = 1,2, . . . . The results obtained in this paper extend some of the existing results and are illustrated ...

We consider forced second order differential equation with p-Laplacian and nonlinearities given by a Riemann-Stieltjes integrals in the form of ( p(t)φγ ( x′(t) ))′ + q0 (t)φγ (x(t)) + ∫ b 0 q (t, s)φα(s) (x(t)) dζ (s) = e(t), where φα (u) := |u| sgnu, γ, b ∈ (0,∞) , α ∈ C [0, b) is strictly increasing such that 0 ≤ α (0) < γ < α (b−), p, q0, e ∈ C ([t0,∞),R) with p (t) > 0 on [t0,∞), q ∈ C ([0...

A Parameter Uniform Numerical Scheme for Singularly Perturbed Differential-difference Equations with Mixed Shifts

In this paper, we consider a second-order singularly perturbed differential-difference equations with mixed delay and advance parameters. At first, we approximate the model problem by an upwind finite difference scheme on a Shishkin mesh. We know that the upwind scheme is stable and its solution is oscillation free, but it gives lower order of accuracy. So, to increase the convergence, we propo...

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.
