John Powe,Michael Lubeck,Zenon Steplewskir generic condition. The results are obtained through the algebraic multiplicities of the system at the singular points. A method for computing the algebraic multiplicity using Newton polygon is also presented.

Third Ventricle and Suprasellar Cisternstions (PDEs) or out of differential consequences of nonlinear PDEs. This includes a complete linearization to an equivalent linear PDE (system) if that is possible. Infinite parameter conservation laws can be computed, for example, with the computer algebra package ..

Darboux Integrability and Limit Cycles for a Class of Polynomial Differential Systems,us polynomials of degree .. Inside this class we identify new subclasses of Darboux integrable systems. Moreover, under additional conditions such Darboux integrable systems can have at most three limit cycles. We provide the explicit expression of these limit cycles.
