Abstract:
The main purpose of this article is to find a criterion for the nonexistence
of formal first integrals for nonlinear systems under general resonance.
An algorithm illustrates an application to a class of generalized
Lokta-Volterra systems. Our result generalize the classical Poincare's
nonintegrability theorem and the existing results in the literature.
