Oscillation criteria for certain forced second-order nonlinear differential equations

Integral averaging technique for the interval oscillation criteria of certain second-order nonlinear differential equations

“…Recently, Agarwal and Grace [1], Li and Agarwal [21] and Li and Cheng [22] established general results for nonlinear forced equations. More recently, Çakmak and Tiryaki [3], using general means along the lines given in [29], proved a more general result which extended the results of Wong [28] and Li and Cheng [22] to more general nonlinear forced equations.…”

Oscillation criteria for forced second-order nonlinear differential equations with damping

“…It is easy to see that [1][2][3][4][5][6][7][8][10][11][12][13][14][15] are not applicable to this example.…”

New Oscillation Results for Forced Second Order Differential Equations with Mixed Nonlinearities

“…It has been shown that many real world problems can be modelled, in particular, by half linear differential equations which can be regarded as a natural generalization of linear differential equations [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. A considerable amount of research has also been done on quasi-linear [15][16][17][18] and nonlinear second order differential equations [19][20][21][22][23].…”
