| Outline of Final Research Achievements |
We considered problems on dimer models, which are certain bipartite graphs on the 2-torus. We first proved that a non-degenerate dimer model can be made consistent without changing its characteristic polygon. For a dimer model with a finite group action, we defineded a natural action of the same group on the associated 3-dimensional toric variety in such a way that the action on the canonical sheaf is trivial. Given a Gorenstein affine toric 3-fold with a gout action, we considered the problem whether there exists an consistent dimer model with a group action corresponding to it. In many cases, we obtained an affirmative answer.
