The topology and isochronicity on complex Hamiltonian systems with homogeneous nonlinearities

open access: yes
In this paper, we study the Hamiltonian differential systems with homogeneous nonlinearity parts on $\mathbb{C}^2$. Firstly, we present a series of topological properties of polynomial Hamiltonian functions, with a particular focus on the characteristics

Higher-Order Strong Isochronism of Cauchy–Riemann Systems with Holomorphic Perturbations of a Linear Center

Differential Equations, 2020
We consider systems of the form $$\dot{x}=-y-P(x,y)$$, $$\dot{y}=x+Q(x,y)$$, where $$P$$ and $$Q$$ are functions holomorphic at the origin whose power series expansions in $$x$$ and $$y$$ do not contain free and linear terms and which satisfy the Cauchy–Riemann conditions.

Isochronous Centers and Foci of Two-Dimensional Holomorphic Differential Systems

Russian Mathematics
Two-dimensional autonomous systems of differential equations of the form ẋ= y P(x, y), ẏ = x + Q(x, y), where P and Q are holomorphic functions of order greater than or equal two are considered. In this work, necessary and sufficient conditions for the existence of an isochronous center or focus are obtained. These conditions are formulated in terms of
