Dd. Bainov et Mb. Dimitrova, OSCILLATORY AND ASYMPTOTIC PROPERTIES OF THE SOLUTIONS OF A CLASS OF OPERATOR-DIFFERENTIAL EQUATION, Journal of mathematical analysis and applications, 189(2), 1995, pp. 491-501
In the present paper a class of operator-differential equations is inv
estigated. Sufficient conditions for boundedness and oscillation of th
e solutions of the equations considered are found. The asymptotic prop
erties of their solutions are investigated. (C) 1995 Academic Press, I
