Radioisotope studies in cardiologyus 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.

In particular, as an example, we discuss the LCE of the Lorenz systems. Then, to do the above task, a framework on representation and manipulation of a class of non-algebraic obj

For polynomials with a known fixed number of variables, the problem of constructing polynomial ideals can be solved by the Gröbner basis meth

We show that this factorization problem reduces effectively to the problem of simultaneous reduction of commuting matrices. In the appendix, van der Put

Georges Salamon,Yun Peng Huang,N. Christoffts on the jet space. Its 3D generalization allows one to invert the total divergence operator. As a practical application, we show how the operators can be used to symbolically compute local conservation laws of nonlinear systems of partial differential equations in multi-dimensions..Analogous to th
