Details of a new technique for obtaining rigorous results concerning t
he global dynamics of nonlinear systems is described. The technique co
mbines abstract existence results based on the Conley index theory wit
h rigorous computer assisted computations. As an application of these
methods it is proven that for some explicit parameter values the Loren
z equations exhibit chaotic dynamics.
