Potential-growth indicator problem in matrix models of population dynamics 1
Klochkova I.N. . Given a set of demographic parameters for a structured model population, the potential-growth indicator, R, is a calculable indicator of growth/decline/equilibrium in the population size. Calculating R enables one to see the asymptotic dynamics without finding the dominant eigenvalue, λ1 , of the projection matrix. It is of applied value whenever available data are insufficient to calibrate the projection matrix. It is long-known that if, in the classic Leslie model, p(λ) denotes the characteristic polynomial, then R = 1− p(1) is quite easy to calculate [1]: R = b1 +
