Isochronicity and normal forms of polynomial systems of ODEsHan, Maoan (Avtor) Romanovski, Valery (Avtor) polynomial systems of ODE`sisochronicitylinearizabilitynormal formsWe propose a generalization of the notion of isochronicity for real polynomial autonomous systems to the case of complex two dimensional systems of ODEs. We study the generalized problem in the case of a quadratic system and a system with homogeneous cubic nonlinearities. Main tools of the study are algorithms of computational algebra based on the Groebner basis theory.20122015-07-10 12:41:38Delo ni kategorizirano50562UDK: 51OceCobissID: 19400712COBISS_ID: 19324168DOI: 10.1016/j.jsc.2011.12.039ISSN pri članku: 0747-7171NUK URN: URN:SI:UM:DK:XSIJAURWsl
