Notes

Here I put some notes which I wrote, but not intend to publish in a journal or put on arXiv (at least for the moment).

1. Greatest common divisors and plane curves
   This manuscript is about relation between greatest common divisors of integer pairs satisfying an algebraic equation and plane curve singularities.

2. Open problems in the wild McKay correspondence
   I collected open problems in the wild McKay correspondence as of June, 2015.
