Chernyshenko // Proceedings 26th European conference on modelling and simulation ECMS 2012, 2012, European council for modelling and simulation, Digitaldruck Pirrot GmbH, May 29 - June 01, pp. 150-156.http://ir.nmu.org.ua/handle/123456789/2010The case of a biological population, which consists of sev-eral sub-populations (different kinds of the population ”so-cial” groups: families, bevies, etc.), has been considered. For description of non-trivial interactions between these groups, a model of ”open the Eigen hypercycle” has been proposed. Its bifurcation analysis for 3-dimension case has been carried out. Ecological interpretation of the results has been discussed.enSystemof ordinary quadratic differential equations, asymp-totic stability, biological populationArticle
