At the Tokyo Institute for Technology (TITech), a mathematics domestic conference is running. TITech is close to my home university, so that I did not reserve a hotel nor a flight.

My presentation was at the first of morning session of algebra session (Session I) at the following building. [see left]

The slides of this presentation are now uploaded at my official web-site, where there exist the ppt file as well as the pdf file. The slides are consisted of two-folds; one is on the gerbes of chiral differential operators and the other is more on recent developtment of mine on motivic nature of chiral algebras of Beilinson and Drinfeld. My points on quantum geometry were almost abbreviated, because the audience must be mostly interested in the chiral Hecke algberas of algebro-geomteric nature; rather than generalized differential geometry.

At the afternoon, I heard two 1-hour talks of representation of W-algebras (by Arakawa), and of polylogs, Eisenstein classes, and p-adic L-functions (by Bannai). Arakawa's talk was on the non-linear vertex algebras and around, including the history such as Victor Kac, Igor Frenkel, Feigin-Frenkel, abd Miura pairs. This talk also emphasized the role of chiralization and Hamiltonian reduction. Bannai's talk was mostly on the movie like demostration of elementary theory of generalized polylogarithm well based on the classic work of Beilinson and Deligne, and the relation to local systems after the Riemann-Hilbert correspondence (but not on the monodromy problem so much). Bannai explained his personal motivation at his student period from the paper by Kazuya Kato on the absence of fundamental theorem.

By the way, the sound of bell-ring insect at night is getting louder in Japan.
