A functional differential
equation, in general, is a relationship in which the rate of change of the state of the
system at time t depends on the state of the system at values of time, perhaps other
than the present.
In this paper, sufficient conditions are given for g so that the initial value
problem y′(t) = F(t,y(g(t))),y(p) = q, may be solved uniquely; where F is
both continuous into the Banach space B, and is Lipschitzean in the second
position.
