More topologies on the set of isomorphism classes of maximal Cohen-Macaulay modules

The title is a reference to a 2019 paper by Naoya Hiramatsu and Ryo Takahashi. This project has started as an investigation of cohomology annihilators in dimension 2 and then it looks like it will become more about these topologies.

Draft available here, comments welcome:
