Oscillation Criteria for Odd Order Neutral Equations

Oscillation of first order neutral differential equations of Euler form

“…, n, has been investigated by many authors. See, for example, [7,12,6,3] and the references cited therein. In particular, it is known [7] (see also [11]) that every solution of Eq.…”

Asymptotic Behavior of Solutions of the Third Order Nonlinear Mixed Type Neutral Differential Equations

“…where τ i , σ i are positive constants for i = 1, 2. It is well known (see [9]) that the differential inequalities (29) and (30) are oscillatory if…”

“…Asymptotic properties of solutions of second/third order differential equations have been subject to intensive research in the literature. This problem for differential equations with respective delays has received a great deal of attention in the last years; see for examples, [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21].…”

Oscillatory Behaviour of First Order Linear Neutral Differential Equations with Distributed Delays

“…Recently many authors have considered the oscillation characteristics of the first neutral differential equations [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15] and give necessary and sufficient conditions for oscillation. Although they obtained many strong resultes, most of them have concentrated their attention on the equations with discrete delays, and only a few authors (see [7][8][9][10][11][12] …”
