Oscillation Criteria for a Class of Second-Order Nonlinear Differential Equations with Damping Term
and Applied Analysis 3 Proof. Assume that 1.1 has a nonoscillatory solution x t . Without loss of generality, suppose that it is an eventually positive solution if it is an eventually negative solution, the proof is similar , that is, x t > 0 for all t ≥ t0. We consider the following three cases. Case 1. Suppose that x′ t is oscillatory. Then there exists t1 ≥ t0 such that x′ t1 0. From 1.1 , w...

where t ≥ t0 ≥ 0, a(t), p(t), q(t) ∈ C ([t0,∞) ;R) and Ψ, k, f ∈ C(R,R). It is also assumed that there are positive constants c, c1, μ and γ such that the following conditions are satisfied: (C1) a(t) > 0 and xf(x) > 0 for all x 6= 0; (C2) 0 < c ≤ Ψ(x) ≤ c1 for all x; (C3) γ > 0 and k(y) ≤ γyk(y) for all y ∈ R; (C4) q(t) ≥ 0, f(x) x ≥ μ > 0 for x 6= 0. We recall that a function x : [t0, t1) → R...
متن کاملOscillation Criteria for Second-order Nonlinear Differential Equations with Damping Term
By employing a generalized Riccati technique and an integral averaging technique, new oscillation criteria are established for a class of second-order nonlinear differential equations with damping term. These criteria extend, improve and unify a number of existing results and handle the cases which are not covered by the known criteria. In particular, several interesting examples that illustrat...
متن کاملInterval Oscillation Criteria for a Class of Nonlinear Fractional Differential Equations with Nonlinear Damping Term
In this paper, based on certain variable transformation, we apply the known (G’/G) method to seek exact solutions for three fractional partial differential equations: the space fractional (2+1)-dimensional breaking soliton equations, the space-time fractional Fokas equation, and the spacetime fractional Kaup-Kupershmidt equation. The fractional derivative is defined in the sense of modified Rie...
متن کاملOscillation Theorems for Second Order Nonlinear Differential Equations with Damping
Some oscillation criteria for solutions of a general ordinary differential equation of second order of the form (r(t)ψ(x(t))ẋ(t))+h(t)ẋ(t)+q(t)φ(g(x(t)),r(t)ψ(x(t))ẋ(t)) = H(t,x(t), ẋ(t)) with alternating coefficients are discussed. Our results improve and extend some existing results in the literature. Some illustrative examples are given with its numerical solutions which are computed using R...
