INVARIANCE (Summational) 5)
← Back
The preservation of number in a population.
According to A.S. IBERALL, who introduces the notion, summational invariance marks a trend which can be verified not by dealing with individuals, but through generations.
IBERALL connects this idea with thermodynamics, which: "… is restricted to what it can describe in an ongoing viable system. It can only deal with variables which preserve fundamental properties upon interaction: so-called cyclic variables, or collisional invariants, or summational invariants" (1973, p.5).
The concept seems related to critical thresholds in composite systems.
