My family and I are all fine.
Thank you very much for your thoughts.

I have been working on mathematical aspects of 2D conformal field theories.
The research topics from new to old are roughly:
- Chiral conformal field theories on Riemann surfaces associated with vertex operator algebras.
- Automophism Groups of Vertex Operator Algebras.
- Representation Theory of Quantum Affine Algebras.
- Knizhnik-Zamolodchikov equation and its variants.
