Linearizability conditions of time-reversible cubic systems
Xingwu Chen, Valery Romanovski
Izvirni znanstveni članek
Oznake: matematika;mathematics;
In this paper we present the necessary and sufficient conditions for linearizability of the planar time-reversible cubic complex system ▫$\dot{x}=x+P(x,y)$▫, ▫$\dot{y}=-y+Q(x,y)$▫. From these conditions, the necessary and sufficient conditions for the origin to be an isochronous center of the time-r ...

In this paper we study the linearizability problem of polynomial-like complex differential systems. We give a reduction of linearizability problem of such non-polynomial systems to the problem of polynomial systems. Applying this reduction, we find some linearizability conditions for a time-reversib ...
