Abstract
Let be a complete local principal ideal ring with residue field of characteristic not and . Take with its reduction . In this article, we study the following lifting problem. Suppose there exists a tuple of pairwise commuting matrices such that ; under what conditions can this solution be lifted to a tuple of pairwise commuting matrices satisfying ? For cyclic, we show that, under suitable hypotheses analogous to those appearing in Hensel lemma, such a lifting is always possible.
