We study a phase portrait of a nonlinear 10-dimensional dynamical system describing a model of functioning of one circular gene network. We find sufficient conditions for the existence of a cycle in this phase portrait. For a similar 18-dimensional dynamical system, we find conditions for the existence of at least two cycles in its phase portrait.
Keywords: nonlinear dynamical systems, circular gene network, torus principle.
Mots-clés : phase portraits, cycles
