Some oscillation criteria for difference equations
Computers & Mathematics with Applications, 2000 Consider the difference equation \[ x_{n+1}- x_n+p_nx_{n-k}=0, \quad n=0,1,2, \dots\tag{1} \] where \(\{p_n\}\) is a sequence of nonnegative real numbers and \(k\) is a positive integer. New sufficient conditions for the oscillation of all solutions of (1) are established.

Oscillation Criteria for Certain Nonlinear Differential Equations
Journal of Mathematical Analysis and Applications, 1999 The author studies the second-order ordinary differential equation \[ x''(t)+p(t)f(x(t))g(x'(t))=0,\tag{1} \] and the delay differential equations \[ x''(t)+p(t)f(x(\tau (t)))g(x'(t))=0\tag{2} \] and \[ x''(t)+p(t)f(x(t),x(\tau (t)))g(x'(t))=0 \tag{3} \] for \(t\geq t_0\).

Oscillation criteria for second-order nonlinear perturbed differential equations
Electronic Journal of Differential Equations, 2014 In this article, we study the oscillation of solutions to the nonlinear second-order differential equation $$ \Big(r(t)\psi(x(t))|x'(t)|^{\alpha-1}x'(t)\Big)' +P(t,x'(t))\psi(x(t))+Q(t,x(t))=0. $$ We obtain sufficient conditions for the oscillation
