Originální název

An explicit criterion for the existence of positive solutions of the linear delayed equation $\dot x(t)=-c(t)x(t-\tau(t))$.

Anglický název

An explicit criterion for the existence of positive solutions of the linear delayed equation $\dot x(t)=-c(t)x(t-\tau(t))$.

Originální abstrakt

The paper investigates an equation with a single delay. The difference $t - \tau (t)$ is an increasing function. Its purpose is to derive a new explicit integral criterion for the existence of a positive solution. An overview of known relevant criteria is provided and relevant comparisons are also given.
