摘要
考虑具有脉冲的离散的红血球补充模型Δx(n)=∑mi=1ri(n)[-μx(n-li)+peqx(n-li)]n≥0n≠nkx(nk+1)-x(nk)=bkx(nk)k=1,2,3,…给出了方程每一个解的振动与存在非振动解的充分条件.
This paper considers the model of a discrete red blood cells with impulses {△x(n) = m∑i=1 ri(n) [-μx(n-li) + peqx(n-li)] n≥0 n≠nk x(nk + 1) - x(nk) = bkx(nk) k=1,2,3,……Sufficient conditions are obtained for the oscillation and nonoscillation of solutions of equation (*).
