Oscillation criteria for even order nonlinear neutral differential equations

Oscillatory behavior of third-order neutral delay differential equations with distributed deviating arguments

“…Over the last several years, an increasing attention has been given to the oscillation theory and asymptotic behavior of various classes of second-order and high-order differential equations and dynamic equations on time scales [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. So far, much research activity concerns the oscillation problem of the third-order (TO) neutral differential and dynamic equations [18][19][20][21][22][23][24][25][26].…”

New oscillation criteria for second-order neutral delay dynamic equations

“…In recent years there has been much research activities concerning the oscillation of solutions of several classes of neutral dynamic equations, see [7,9,10,12] Several papers are devoted to study the cases in which 0 < p(t) < 1 and 0 < p(t) ≤ p 0 < ∞, for instance, in case of T = R Baculíková and Džurina [2] studied the second order neutral differential equation…”

Oscillation Criteria for Certain Even Order Neutral Delay Differential Equations

“…During the last 20 years, significant efforts have been devoted to investigate the oscillatory behaviour of neutral differential equations; see [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] and the references cited therein. In particular, (1) and related forms have been considered by several authors; see [10,11,13,14,16]. Several recent results are surveyed in Sun et al [13].…”

“…In particular, (1) and related forms have been considered by several authors; see [10,11,13,14,16]. Several recent results are surveyed in Sun et al [13]. In addition, we refer to [3][4][5]8], where the oscillatory behaviour of solutions of (1) with = 2 was studied.…”
