Polynomial Vector Fields on Algebraic Surfaces of Revolution

Results in Mathematics, 2020
The authors study polynomial vector fields of arbitrary degree in \(\mathbb{R}^3\) having an algebraic surface of revolution invariant by their flows. Subsequently, they restrict their attention to an important case where the algebraic surface of revolution is a cubic surface and characterize all the possible configurations of invariant meridians and ...

Invariant theory of planar polynomial vector fields

2021
The roots of the invariant theory of polynomial vector fields lie in the classical invariant theory. The idea to adapt to polynomial vector fields the concepts of classical invariant theory is due to C. S. Sibirschi, the founder of the Chisinau school of qualitative theory of differential equations.
