摘要
We show that the condition vertical bar a vertical bar + vertical bar Sigma(+)(l=0)vertical bar < 1 is not necessary, though sufficient, for the asymptotic stability of x(n+1) ax(n) +Sigma(+)(l)(=0) b(n-1x1). We prove the existence of a class of Volterra difference equations (VDEs) that violate this condition but whose zero solutions are asymptotically stable.
