摘要
利用积分方程理论,对已有结果“胎次递进人口算子A生成的半群T(t)在t≥M时是紧半群”,在不对λ_0(s)加限制条件的情况下,简化了其证明过程,并对上述结果有所改进。
By the integral equation theory, the proof for compact semigroup T(t) generated by the parity progressive population operator A is simplified without any restriction on λ0(s), and the result mentioned above is improved.
