On the Three Properties of Stationary Populations and knotting with
We propose three properties that are related to the stationary population
identity (SPI) of population biology by connecting it with stationary
populations and non-stationary populations which are approaching stationarity.
These properties provide deeper insights into cohort formation in real-world
populations and the length of the duration for which stationary and
non-stationary conditions hold. The new concepts are based on the time gap
between the occurrence of stationary and non-stationary populations within the
SPI framework that we refer to as Oscillatory SPI and the Amplitude of SPI.
