Structured population models, conservation laws, and delay equations

[摘要] The general principles by which certain structured population models or renewal equations can be reduced to ordinary differential equations or delay equations are systematically investigated with particular attention to retarded and neutral delay differential equations. Approriate state spaces are defined and their relations are studied, as well as the positivity of the resulting evolutionary systems. (C) 2000.
