Stability conditions for reversible and partially integrable systems

Abstract

The purpose of this paper is to provide results like Peixoto’s Theorem inside a class (Formula presented) of 3-dimensional reversible systems. We deal with reversible systems associated to an involution φ1 such that Dim Fix(φ1) is equal to one. We further assume the existence of a first integral for any X ∈ (Formula presented) that leaves invariant any sphere centered at the origin. The main result establishes generic necessary conditions for the structural stability in (Formula presented). Stability conditions on generic one-parameter families of reversible vector fields on the two-dimensional sphere are also stated.
