Centers of projective vector fields of spatial quasi-homogeneous systems with weight $(m,m,n)$ and degree $2$ on the sphere
In this paper we study the centers of projective vector fields $\mathbf{Q}_T$ of three-dimensional quasi-homogeneous differential system $d\mathbf{x}/dt=\mathbf{Q}(\mathbf{x})$ with the weight $(m,m,n)$ and degree $2$ on the unit sphere $\mathbb{S}^2$. We seek the sufficient and necessary conditions...
