CONUNDRUMS FOR CONTINUOUS LEBESGUE MEASURE-PRESERVING INTERVAL MAPS
Résumé
We consider continuous maps of the interval which preserve the Lebesgue measure. Except for the identity map or $1 - \id$ all such maps have topological entropy at least $\log2/2$ and generically they have infinite topological entropy. In this article we show that the generic map has zero measure-theoretic entropy. This implies that there are dramatic differences in the topological versus metric behavior both for injectivity as well as for the structure of the level sets of generic maps.
