Analytic Nilpotent Centers on Center Manifolds

Claudio Pessoa, Lucas Queiroz

Consider analytical three-dimensional differential systems having a singular point at the origin such that its linear part is $y \partial_{x} - λ z \partial_{z}$ for some $λ \neq = 0$ . The res…

Monodromic nilpotent singular points with odd Andreev number and the center problem

Claudio Pessoa, Lucas Queiroz

Given a nilpotent singular point of a planar vector field, its monodromy is associated with its Andreev number $n$ . The parity of $n$ determines whether the existence of an inverse…
