On the integrability and the zero-Hopf bifurcation of a Chen-Wang differential system
(SpringerDordrecht, 2015-04)
The first objective of this paper was to study the Darboux integrability of the polynomial differential system
'X PONTO' = y, 'Y PONTO' = z, 'Z PONTO' = −y − 'X POT.2' − xz + 3'Y POT.2' + a,
and the second one is to ...
Integrability and Dynamics of Quadratic Three-Dimensional Differential Systems Having an Invariant Paraboloid
(2016-07-01)
Invariant algebraic surfaces are commonly observed in differential systems arising in mathematical modeling of natural phenomena. In this paper, we study the integrability and dynamics of quadratic polynomial differential ...
The center problem for a 1 : -4 resonant quadratic system
(Academic Press/ElsevierSan Diego, 2014-12-15)
The main objective of this paper is to find necessary and sufficient conditions for a 1 : −4 resonant system of the form 'X PONTO' = x − 'A IND.10' 'X POT.2' − 'A IND.01' xy − 'A IND.12' 'Y POT.2', 'Y PONTO' = −4y + 'B ...
