Periodic orbits for a class of reversible quadratic vector field on R-3
(Elsevier B. V., 2007-11-15)
For a class of reversible quadratic vector fields on R-3 we study the periodic orbits that bifurcate from a heteroclinic loop having two singular points at infinity connected by an invariant straight line in the finite ...
