Painleve III($D_8$)tau函数的Backlund变换

Backlund transformation of Painleve III($D_8$) tau function

M. A. Bershtein, A. I. Shchechkin

摘要:

本文研究了Painlevé III($D_8$)$τ$函数在中心荷为$1$的Virasoro共形块中的显式公式(Gamayun,Iorgov,Lisovyy提出).潘勒韦方程有两类双线性形式,我们称之为Toda-like和Okamoto-like。我们利用两个维拉索罗代数的直和在某个超代数中的嵌入,从表示论中得到了这些方程。这两类双线性型对应于该代数的Neveu-Schwarz扇区和Ramond扇区。我们还获得$τ$函数的代数解Painlevé III($D_8$)的维拉索罗代数的特殊表示的最高权$(n+1/4)^2$。

英文摘要:

We study explicit formula (suggested by Gamayun, Iorgov, Lisovyy) for Painlevé III($D_8$) $τ$ function in terms of Virasoro conformal blocks with central charge $1$. The Painlevé equation has two types of bilinear forms, we call them Toda-like and Okamoto-like. We obtain these equations from the representation theory using an embedding of a direct sum of two Virasoro algebra in a certain superalgebra. These two types of bilinear forms correspond to Neveu-Schwarz sector and Ramond sector of this algebra. We also obtain $τ$ functions of algebraic solutions of Painlevé III($D_8$) from the special representations of the Virasoro algebra of highest weight $(n+1/4)^2$.
