On the momentum of pseudostable populations
BACKGROUND: Keyfitz introduced in 1971 the “population momentum” – that is, the amount of further population growth (decline) if an instantaneous reduction (increase) of fertility to the replacement level occurred in a stable population. OBJECTIVE: We wanted to find analytical results for the momentum of pseudostable populations – that is, populations that relax the strict assumptions of the stable population model and allow fertility reductions …
Petrarch's canzoniere
The paper is concerned with a celebrated collection of love poems, the 14th century Italian poet Francis Petrarch's Canzoniere. A striking feature of these poems is the emotional ups and downs experienced by Petrarch and his platonic mistress Laura. Recently, attempts have been made to model these emotional swings by catastrophe theory or nonlinear differential equations. This paper takes a different approach. Starting with a pair of differential…
