Nonrigidity for circle homeomorphisms with several break points

Abdelhamid Adouani, Habib Marzougui

Let $f$ and $g$ be two class $P$ -homeomorphisms of the circle $S^{1}$ with break points singularities. Assume that the derivatives $Df$ and $Dg$ are absolutely co…

A sharp smoothness of the conjugation of class P-homeomorphisms to diffeomorphisms

Abdelhamid Adouani, Habib Marzougui

Let f be a class P -homeomorphism of the circle. We prove that there exists a piecewise analytic homeomorphism that conjugate f to a one-class P with prescribed break points lying…
