Dynamical asymmetry is -typical
Amie Wilkinson (Chicago)
here is an unrelated string of tex: A {\em bifoliated plane} is a plane together with a pair of topologically transverse foliations , possibly with isolated prong singularities.
We assume throughout this work that bifoliated planes have no {\em infinite horizontal rectangles}, that is, no properly embedded subset isomorphic to with its horizontal and vertical product foliation.
