The Newhouse phenomenon has a codimension 2 nature. Namely, there exist codimension 2 laminations of maps with infinitely many sinks. The leaves of the laminations are smooth and the sinks move simultaneously along the leaves. These Newhouse laminations occur in unfoldings of rank-one homoclinic tangencies. As a consequence, in the space of polynomial maps, there are examples of: The first lecture will discuss topological aspects of two dimensional dynamics. This part will give a context for the Newhouse Laminations. The second part will discuss in more detail the construction of the Newhouse Laminations.
