| Abstract | |
In the space of C-k piecewise expanding unimodal maps, k >= 1, we characterize the C-1 smooth families of maps where the topological dynamics does not change ( the ``smooth deformations{''}) as the families tangent to a continuous distribution of codimension-one subspaces (the ``horizontal{''} directions) in that space. Furthermore such codimension-one subspaces are defined as the kernels of an explicit class of linear functionals. As a consequence we show the existence of Ck-1+(Lip) deformations tangent to every given C-k horizontal direction, for k >= 2. (AU) | |
