Abstract
In this manuscript, we formulate the differential Hurwitz tree obstructions for the refined local lifting problem. We specifically explore the circumstances under which these obstructions vanish for cyclic covers. The constructions presented in this paper will be used to address the refined local lifting problem in our forthcoming works.
