We have decided to discontinue the publication of preprints on our preprint server as of 1 March 2024. The publication culture within mathematics has changed so much due to the rise of repositories such as ArXiV (www.arxiv.org) that we are encouraging all institute members to make their preprints available there. An institute's repository in its previous form is, therefore, unnecessary. The preprints published to date will remain available here, but we will not add any new preprints here.

Divisor class groups of rational trinomial varieties
We give an explicit description of the divisor class groups of rational trinomial varieties. As an application we show the connection between the iteration of Cox rings of varieties with torus action of complexity one of arbitrary dimension to the iteration of Cox rings of the Du Val surfaces.
