Journal ArticleDOI
On existence of positive solutions and bounded oscillations for neutral difference equations
B. S. Lalli,B. G. Zhang +1 more
TL;DR: In this paper, a criterion for the existence of a positive solution for the first order difference equation Δ(n − cxn − m) + pnxn − k = 0, pn ⩾ 0 is established.
Journal ArticleDOI
Addendum: Oscillation Theorems for Nonlinear Second-Order Differential Equations with a Nonlinear Damping Term
TL;DR: In this paper, sufficient conditions for the oscillation of the nonlinear second order differential equation were established, and a systematic study was attempted which extends and correlates a number of existing results. But none of the results were considered in this paper.
Journal ArticleDOI
On the oscillation of solutions and existence of positive solutions of neutral difference equations
TL;DR: In this article, the authors obtained sufficient conditions for the oscillation of all solutions and existence of positive solutions of the neutral difference equation Δ (x n + cx n − m ) + p n x n − k = 0.
Journal ArticleDOI
Integral averaging techniques for the oscillation of second order nonlinear differential equations
Said R. Grace,B. S. Lalli +1 more
TL;DR: In this article, the authors established new oscillation criteria for second order nonlinear differential equations of the form if(a(t) ψ(x(t)) ẋ(t)),suẋ + p(t), Ẇ(t)+ q(t + f(x,t)) = 0 for all large values of t. These criteria are obtained by using integral averaging techniques.
Journal ArticleDOI
Oscillation theorems for nth-order delay differential equations
Said R. Grace,B. S. Lalli +1 more
TL;DR: In this article, the generalized Emden-Fowler equation with retarded arguments was extended and improved with fundamental oscillation criteria for superlinear, sublinear, and linear differential equations.
