Populations That Are Not Age-Dependent,s book starts with problems in which age, as well as most other features of real populations, is disregarded, and in which outcomes are taken as deterministic rather than stochastic. A brief introduction presents some of the mathematical concepts of this first preliminary chapter and defines the notation in which the problems are expressed.
