Asymptotic behavior of an odd-order delay differential equation
Li, Tongxing; Rogovchenko, Yuriy V. (Journal article; Peer reviewed, 2014)We study asymptotic behavior of solutions to a class of odd-order delay differential equations. Our theorems extend and complement a number of related results reported in the literature. An illustrative example is provided. -
Asymptotic behavior of higher-order quasilinear neutral differential equations
Li, Tongxing; Rogovchenko, Yuriy V. (Journal article; Peer reviewed, 2014)We study asymptotic behavior of solutions to a class of higher-order quasilinear neutral differential equations under the assumptions that allow applications to even- and odd-order differential equations with delayed and ... -
Dynamics of a single species in a fluctuating environment under periodic yield harvesting
Hasanbulli, Mustafa; Rogovchenko, Svitlana P.; Rogovchenko, Yuriy V. (Journal article; Peer reviewed, 2013)We discuss the effect of a periodic yield harvesting on a single species population whose dynamics in a fluctuating environment is described by the logistic differential equation with periodic coefficients. This problem ... -
Oscillation of second-order neutral differential equations
Li, Tongxing; Rogovchenko, Yuriy V.; Zhang, Chenghui (Journal article; Peer reviewed, 2013)We study oscillatory behavior of a class of second-order neutral differential equations relating oscillation of these equations to existence of positive solutions to associated first-order functional differential inequalities. ... -
Oscillation results for second-order nonlinear neutral differential equations
Li, Tongxing; Rogovchenko, Yuriy V. (Journal article; Peer reviewed, 2013)We obtain several oscillation criteria for a class of second-order nonlinear neutral differential equations. New theorems extend a number of related results reported in the literature and can be used in cases where known ... -
Oscillation theorems for second-order nonlinear neutral delay differential equations
Li, Tongxing; Rogovchenko, Yuriy V. (Journal article; Peer reviewed, 2014)We analyze the oscillatory behavior of solutions to a class of second-order nonlinear neutral delay differential equations. Our theorems improve a number of related results reported in the literature. -
Oscillatory behavior of second-order nonlinear neutral differential equations
Li, Tongxing; Rogovchenko, Yuriy V. (Journal article; Peer reviewed, 2014)We study oscillatory behavior of solutions to a class of second-order nonlinear neutral differential equations under the assumptions that allow applications to differential equations with delayed and advanced arguments. ...
