文摘It is known that determination of the stability of neutral differential systems is a difficult and complicated problem, on which little material has been published so far. In [1]—[4], the stability of neutral differential systems had been investigated, with the general result that the delay Δ(t) needs to satisfy 0<Δ0≤Δ(t)≤Δ.
