Query: Cauchy problem for quasilinear systems of functional differential
  equations   We use the contracting mapping principle for proving that under some mild
restrictions the Cauchy problem for quasilinear systems of functional
differential equations with retarded arguments has the unique solution. As a
consequence from this result we obtain that the Cauchy problem for linear
systems of functional differential equations with locally integrable
coeffcients and with locally measurable retarded arguments has the unique
solution. We show that similar results can be obtained for the Cauchy co
problem of quasilinear systems of functional differential equations with
advanced arguments.
