โœฆ Synopsis

General conditions guaranteeing the nonnegativity of solutions of delay differential equations are proposed, Some examples when the nonnegativity is not preserved in time are given. The nonnegativity of solutions of the logistic equation with time delay is considered. Behaviour like in discrete time case is observed. (~) 2000 Elsevier Science Ltd. All rights reserved.
