摘要
In this paper, we investigate the linearizability problem for the two-dimensional planar complex system. (x) over dot = x(1 - a(10)x - a(01)y - a(20)x(2) - a(11)xy - a(02)y(2)), (y) over dot = -y(1 - b(10)x - b(01)y - b(20)x(2) - b(11)xy - b(02)y(2)). The necessary and sufficient conditions for the linearizability of this system are found. From them the conditions for isochronicity of the corresponding real system can be derived.
