Casual Dinner on 5/31 (Fri.)
We are going to have dinner together at some casual restaurant on 5/31 (after Geometry Colloquium).
If you would like to attend this dinner, please let us know via email (k-hayano[at]math[dot]keio[dot]ac[dot]jp).
Please note that we do not intend to pressure those who send emails to attend the dinner: we merely would like to know an approximate number of participants in order to make reservation effectively.
