Метод функции стохастической чувствительности в анализе модели популяционной динамики

Abstract

The paper considers a population model that takes into account the intraspecific competition of prey and the nonlinearity of reproduction of predator populations. Depending on bifurcation parameters the equilibrium and oscillation regimes of the coexistence of populations are studied. The paper simulates different type of noise. Based on the stochastic sensitivity function technique the sensitivity of attractors and stochastic phenomena are studied.
