中性微分-差分方程d/(dt)(x(t)-Cx(t-τ))=Ax(t)+Bx(t-τ)的渐近稳定性

The stability of neutral differential difference equation with real coefficients d/dt(x(t)-CX(tgτ))=AX(t)+BX(t-τ) (τ≥0,constand) (1) has been discussed in [1]. It is noted that there exist τ(A, B, C)>0 such that theasymptotic stability of trival solution of(1)and that of
