Liénard systems and potential-Hamiltonian decomposition. II: Algorithm (Q868973)

The authors propose a method for choosing a decomposition of a system of ordinary differential equations on the plane that models a biological phenomenon into the sum of a gradient and a Hamiltonian vector field. The division of parameters appearing in separate parts then elucidates the roles that they play in the underlying biological system. For part I see: ibid., No. 2, 121-126 (2007; Zbl 1111.37011). For part III see: ibid., No. 4, 253--258 (2007; Zbl 1111.37012).
