摘要
本文讨论了二维人口算子A+B的谱特性,以及由它生成的C_0-半群的性质,导出了相应的积分微分方程组的解及其渐近性质。
In this paper the spectral properties of the two-dimensional popularity operator A + B and the properties of the C_0- Semigroup generated by A + B are analyzed. The solution to the integral-dif-ferential equation is therefrom given. The asymptotic behavior of this solution is also discussed.
