$J$-Stability of immediately expanding polynomial maps in $p$-adic dynamics

Junghun Lee

Given a family $\{f_{\lambda }{\}}_{\lambda \in \Lambda }$ of polynomial maps of degree $d$ where $\Lambda$ is the set of parameters, a polynomial map $f_{{\lambda }_0}$ is called {\it $J$-stable in $\Lambda$} if there exist…
