Local and global properties of nonautonomous dynamical systems and their application to competition models
V. G. Il'ichev Rostov State University
Abstract:
We develop the inheritance principle for local properties by the global Poincare mapping of nonautonomous dynamical systems. Namely, if a semigroup property is uniformly locally universal then it is enjoyed by the global Poincare mapping. In studying the global dynamics of competitors in a periodic medium, the crucial role is played by the multiplicative semigroup of the so-called sign-invariant matrices. We give geometric criteria for stability of equilibria (periodic solutions) in competition models.
Keywords:
universality, semigroup, coarseness, sign-invariant matrices, competition, global stability.
