Polynomial Vector Fields on Algebraic Surfaces of Revolution
Results in Mathematics, 2020The 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 ...

On the isoclines of polynomial vector fields
Siberian Mathematical Journal, 1994The author considers autonomous systems (1) \(\dot x = P(x,y)\), \(\dot y = Q(x,y)\) with \(\{P(x,y), Q(x,y)\}\) a polynomial vector field. He proves the following results. Theorem 1. Assume \(P(x,y) = P_m (x,y) + P_n (x,y)\), \(Q(x,y) = Q_m (x,y) + Q_n (x,y)\) with \(m,n > 0\) and \(P_m\), \(Q_m\) and \(P_n\), \(Q_n\) homogeneous polynomials of degree

Polynomial vector fields on the torus
Boletim da Sociedade Brasileira de Matemática, 1986In this paper it is shown that the structurally stable polynomial vector fields on the torus \(T^ 2\), with singularities, are open and dense in the set of such vector fields. Many kinds of distinct dynamical phenomena are also presented by a list of examples including the Cherry flows.

On Muldowney’s Criteria for Polynomial Vector Fields with Constraints
2011We study Muldowney's extension of the classical Bendixson-Dulac criterion for excluding periodic orbits to higher dimensions for polynomial vector fields. Using the formulation of Muldowney's sufficient criteria for excluding periodic orbits of the parameterized vector field on a convex set as a quantifier elimination problem over the ordered field of ...

A globally asymptotically stable polynomial vector field with no polynomial Lyapunov function
IEEE Conference on Decision and Control and European Control Conference, 2011We give a simple, explicit example of a two-dimensional polynomial vector field that is globally asymptotically stable but does not admit a polynomial Lyapunov function.

On a Polynomial Vector Field Model for Shape Representation
2006In this paper we propose an efficient algorithm to perform a polynomial approximation of the vector field derived from the usual distance mapping method. The main ingredients consist of minimizing a quadratic functional and transforming this problem in an appropriate setting for implementation.
