Today and yesterday are days for proving. I and N~ Peam trying to proof the necessary and sufficient condition for regraspable between two parallel grasps. The process is quite fun, working with Peam and Fu on this subject really make research much more fun. Maybe that is what they called "atmosphere of research". However, if a proof does not come out, the world much be worse.
Just talk with Ai kong (burin) about staying at his apartment, my dear fat ขี้งอน old friend. I will stay with him on sat. 2/9 to wed. 6/9. Ai Kong, of course, request a sweet from sendai. Here is the page ขนม. Click on 萩の月 (hagi no tsuki) and that's it. The pictures look very delicious. Ah, my mind already fixed on eating at Japan, what a nice place for eating.
