Title: On the Three Properties of Stationary Populations and knotting with Non-Stationary Populations,
Abstract: 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.
