In this talk, we shall discuss the semi-infinite variation of Hodge structure associated to real valued solutions of a Toda equation.
First, we describe a classification of the real valued solutions of the Toda equation in terms of their parabolic weights, from the viewpoint of the Kobayashi-Hitchin correspondence for wild harmonic bundles. Then, we discuss when the associated semi-infinite variation of Hodge structure has an integral structure.
It follows from two results. One is the explicit computation of the Stokes factors of a certain meromorphic flat bundle. The other is an explicit description of the associated meromorphic flat bundle. 
We use the opposite filtration of the limit mixed twistor structure with an induced torus action.

  1. Regularization by noise in nonlinear evolution equations

    There are some phenomena called "regularization by noise" in nonlinear evolution equations. This means that if you add a noise to the system, the system would have a better property than without noise. As one of examples, I will explain this...
