OSCILLATIONS OF NEUTRAL FUNCTIONAL DIFFERENTIAL EQUATIONS

Acta Mathematica Scientia, 1992
This paper presents sufficient conditions for all the solutions of some classes of neutral functional differential equations (NFDE) to oscillate. Under consideration are (i) a class of NFDE of retarded type \[ [x(t)- px(t-\tau)]'+\sum^ n_{i=1}q_ ix(t-\sigma_ i)=0, \tag{1} \] where \(p\geq 0\), \(\tau\), \(q_ i\) and the \(\sigma_ i\) are positive ...

Relative Controllability of Neutral Differential Equations with a Delay

SIAM Journal on Control and Optimization, 2017
The problem of relative controllability for linear systems of neutral differential equations with a delay is investigated. An equivalent condition of Kalman type is proved. All the control functions leading the system from an initial state to a desired arbitrary point are characterized in terms of shifted Legendre polynomials.

LOGISTIC DIFFERENTIAL EQUATION OF NEUTRAL TYPE

1997
The following logistic neutral functional-differential equation describes some type of population dynamics (consistent with the experiment on the population of Daphnia magna) accounting retardation due to the processes of growing up and maturation: \[ N'=rN\left(1- {N(t-h)+\rho N'(t-h)\over K}\right) . \] The boundedness and asymptotic stability of its
