Strange attractors across the boundary of hyperbolic systems

We study a bifurcation of Axiom A (hyperbolic) vector fields in dimension t hree leading to robust strange attractors with singularities. The Axiom A V ector fields involved in the bifurcation exhibit a basic set equivalent to the suspension of a three symbol subshift. The attractors arising from this kind of bifurcation are not equivalent to the geometric Lorenz attractors.
