Deviations from $S$-Integrality in Orbits on $P^N$

ABSTRACT

Silverman proved that when the second iterate of a rational function $\varnothing$ is not a polynomial, there are only finitely many $S$-integral points in each orbit of a rational point. We will survey prior results that attempt to generalize this result to higher-dimensions, and then we will discuss an improvement of them. All of these general theories assume some version of a very deep Diophantine conjecture by Vojta. We will also give some examples of maps for which these general theories do not apply directly but for which deviations from $S$-integrality in orbits can be analyzed unconditionally. We will end by posing many questions still to be answered.
