Transverse Homoclinic Connections for Geodesic FlowsGiven a two dimensional Riemannian manifold for which the geodesic flow has a homoclinic (heteroclinic) connection, we show how to make a .. small perturbation of the metric for which the connection becomes transverse. We apply this result to several examples.

Analytic Torsion, Flows and FoliationsWe present an overview of the known results in Lefschetz formulas for flows, that is, on the problem of relating the topology of a manifold to the number and nature of periodic orbits of a vector field.

The Global Phase Structure of the Three Dimensional Isosceles Three Body Problem with Zero EnergyWe study the global flow defined by the three-dimensional isosceles three-body problem with zero energy. A new set of coordinates and a scaled time are introduced which alow the phase space to be compactified by adding boundary manifolds. Geometric argument gives an almost complete sketch of the global phase portrait of this gravitational system.

Complementing the work of Alhassid .. and Ganesan and Lakshmanan, we show that the global flow is characterized by three parametric bifurcations of butterfly type corresponding to the dynamical symmetries of the problem.
