The Japan Math-Phys Society became separated after the Nobel winning paper by Yukawa at about 75 years ago. So my presentation to JPS (Japan Physical Society) is the first time since I did at the year 2006; which was a joint meeting with USA at Hawaii. (See the past blog.)
In this week, I visited the Kyushu-Kogyo University by staying only 2(+1) days in a hotel near Kokura (小倉:bullet train station). The travel was nice, because I took a very-early-morning flight from Haneda to Kita-Kyushu; my flight was the retirement of the aircraft (type MD87) for 25 years, whose schedule for departure was 5 minute delayed, but the arrival was just on time. (The speed of flight was 820 km/hour: the second figure is the Kohu-basin 甲府盆地) Then the third figure is the mono-rail and bullet-train station Kokura seen from the station square.

The second day was by the lattice gauge theory, quantum integrable systems, AdS/CFT, and quantum mechanics. I heard some physics discussions by senior staffs, and I had become very exhausted.
The final day was my presentation day at the string theory session, for the illumination of my past 2-3 years of development of "pure math" to see how the S-duality conjecture is seen from an algebraic-geometer with some physics background. The slide is available at:
Moduli space of chiral conformal field theories and compactification to Kahler manifolds
The final figure is the panel guiding the participants to the presentation halls.
