Existence of periodic points near an isolated fixed point with Lefschetz index $1$ and zero rotation for area preserving surface homeomorphisms

Jingzhi Yan

Let $f$ be an orientation and area preserving diffeomorphism of an oriented surface $M$ with an isolated degenerate fixed point $z_{0}$ with Lefschetz index one. Le Roux conjectured…

Existence of torsion-low maximal identity isotopies for area preserving surface homeomorphisms

Jingzhi Yan

The paper concerns area preserving homeomorphisms of surfaces that are isotopic to the identity. The purpose of the paper is to find a maximal identity isotopy such that we can giv…
