Problem statement
Given an F-finite F-module, how can one efficiently compute a unit F-module? For example, given the map , how can one find a root for the local cohomology module ?

Background
Question context
If R is a regular ring of characteristic p, then the local cohomology modules have many nice finiteness properties; one can describe many of these properties via the theory of unit -modules. Work on implementing these calculations in M2 was begun at the 2023 Minneapolis workshop.
