Darboux integrability of a nonlinear financial system

Applied Mathematics and Computation, 2011
The author studies a nonlinear system with some parameters considered by Junhai and Chen (2001) (a system of nonlinear autonomous ordinary differential equations in \(\mathbb R^2\)) describing the time variations of three state variables: the interest rate, the investment demand, and the price index.

EXPONENTIAL FACTORS AND DARBOUX INTEGRABILITY FOR THE RÖSSLER SYSTEM

International Journal of Bifurcation and Chaos in Applied Sciences and Engineering, 2004
We characterize all generators of the exponential factors for the Rössler system by using weight homogeneous polynomials and the method of characteristic curves for solving linear partial differential equations. Moreover, using Darboux polynomials and exponential factors we obtain the necessary and sufficient conditions in order that the Rössler ...

DARBOUX INTEGRABILITY FOR THE RÖSSLER SYSTEM

International Journal of Bifurcation and Chaos, 2002
In this note we characterize all generators of Darboux polynomials of the Rössler system by using weight homogeneous polynomials and the method of characteristic curves for solving linear partial differential equations. As a corollary we prove that the Rössler system is not algebraically integrable, and that every rational first integral is a rational
