We investigate the many-particle and mean-field correspondence for a non-Hermitian N-
particle Bose-Hubbard dimer where a complex on-site energy describes an effective decay …

We investigate an open Bose–Hubbard dimer with a non-Hermitian term represents an
asymmetric coupling between the two sites. By mapping to the collective angular moment …

In this paper, we characterize and study dynamical properties of cubic vector fields on the
sphere S 2={(x, y, z)∈ R 3| x 2+ y 2+ z 2= 1}. We start by classifying all degree three …

We study a class of quadratic reversible polynomial vector fields on S2 with (3, 2)-type
reversibility. We classify all isolated singularities and we prove the nonexistence of limit …

This paper is devoted to the complete classification of global phase portraits for reversible
equivariant Hamiltonian systems of linear plus quartic homogeneous polynomials. Such …

This paper study the planar semi-quasi homogeneous polynomial differential systems
(PSQHPDS), which can be regarded as a generalization of semi-homogeneous and of quasi …

A quadratic polynomial differential systemcan be identified with a single point of ℝ 12
through its coefficients. The phase portrait of the quadratic systems having a rational first …

Let X be a polynomial vector field of degree n on M, M= ℝm. The dynamics and the algebraic-
geometric properties of the vector fields X have been studied intensively, mainly for the case …
