Abstract
This article analyzes the continuum-mechanical representation of the global invariant geometric properties of 2D time-periodic Hamiltonian systems and chaotic flows. An application of this analysis concerns the evolution in t ime of the invariant measure associated with the space-filling properties o f the invariant unstable foliation related in laminar chaotic flows to the pointwise intermaterial contact-area density between fluid elements.
