Darboux first integrals of Kolmogorov systems with invariant $n$ -sphere

Supriyo Jana, Soumen Sarkar

In this paper, we characterize all polynomial Kolmogorov vector fields for which the standard $n$ -sphere is invariant. We exhibit completely integrable Kolmogorov vector fields of…

Dynamics and integrability of polynomial vector fields on the $n$ -dimensional sphere

Supriyo Jana, Soumen Sarkar

In this paper, we characterize arbitrary polynomial vector fields on $S^{n}$ . We establish a necessary and sufficient condition for a degree one vector field on the odd-dimensional s…

Characterization and dynamics of certain classes of polynomial vector fields on the torus

Supriyo Jana

In this paper, we classify all polynomial vector fields in $R^{3}$ of degree up to three such that their flow makes the torus $$\mathbb{T}^2=\{(x,y,z)\in \mathbb{R}^3:(x^2+y…

Invariant circles and phase portraits of cubic vector fields on the sphere

Joji Benny, Supriyo Jana, Soumen Sarkar

In this paper, we characterize and study dynamical properties of cubic vector fields on the sphere $S^{2} = {(x, y, z) \in R^{3} ∣ x^{2} + y^{2} + z^{2} = 1}$ . We start by…
