Happy new year from Japan!

In Japan, where the time is defined as the eastest (+9:00 hour), we are now about to finish the year 2008 and welcome the year 2009. The above photo is a Japanese style decoration of happy new year.

The ending of the year 2008

In Japan, it is about to finish the end of 30th of December, 2008.

I went to the Komaba campus, and then to the Shibuya station, in order to work through the academic works as well as some shopping of digital devices.

The photos are what the Komaba campus of the University of Tokyo looks like at the end of the year of European calender.

Langlands correspondence for loop groups

Today I went to IPMU to discuss the abstract idea of geometric Langlands program from geometric conformal field theory.

The above picture is what the train station provides for the WiFi wireless LAN at the station or inside the train.

Have a good holiday!

Edward Frenkel (not Igor Frenkel) and my conjecture

We will have an informal seminar on the books of Edward Frenkel at tomorrow and the day after tomorrow.

I will try to comment on the definition, the meaning, and the significance of the Beilinson-Drinfeld chiral algebra theory for (twisted) loop groups and its foundation and applications to geometric representation theory and even mathematical physics of quantum cosmology beyond the standard model with or without Higgs boson(s) (or even Higgsinos?).

My originarity is on the conjecutre of quantum (q-analogue of Poisson bracket) version of geometric Langlands program, which was proposed by me (Makoto Sakurai) at the Strings 2005 conference, Toronto.

Xmas Festival and Newtonian birthday

I went to Shibuya to first eat and then drink.

So, what did we learn about the quantum universe of gravity?
Do we believe in God or in human?

Of course, I am talking about some moonshiny topics.

IPMU miniworkshop: A New Recursion from Random Matrices and Topological String Theory

Today we have an opportunity to meet our friends working on the algebro-geometry, the symplectic geometry, and some topological string theory:

Here Bertrand Eynard (Saclay) a little informally introduced some historical aspects of matrix models of Kontsevich-Witten and Mulase was more on the algebraic geometry of the characteristic classes of Hodge bundles on the Deligne-Mumford compactification of stable maps.

We also heard the talk of Akaho on the immersion version of Floer theory of Fukaya category of $A_{\infty}$-algebra structure, which look alike the intersecting branes of recent topological string theory (of A-model by FOOO (2008)).
