摘要

We develop a continued fraction algorithm in finite extensions of \({\mathbb {Q}}_p\) Q p generalising certain algorithms in \({\mathbb {Q}}_p\) Q p , and prove the finiteness property for certain small degree extensions. We also discuss the metric properties of the associated continued fraction maps for our algorithms using subsequence ergodic theory and moving averages.
