Future Summary
Let us see a simple example that shows that for a fertility function distributed along an age interval, we have damped growth cycles with a period equal to the age α.
On the weak solutions of the McKendrick equation: Existence of demography cycles
Therefore, the pattern of growth of a population with several fertile age classes is almost periodic with several periodicities or frequencies.
On the weak solutions of the McKendrick equation: Existence of demography cycles
If the dispersion of the fertility around the maximal fertility age class is large, the pattern of growth is almost periodic in time.
On the weak solutions of the McKendrick equation: Existence of demography cycles
If, in addition, we consider time variations in the fertility function and mortality modulus, the pattern of growth can show strong fluctuations deviating from the periodic or exponential growth.
On the weak solutions of the McKendrick equation: Existence of demography cycles
The period of these cycles is equal to the age of the first fertile age class.
