广义Jacobi权的Painlevé VI和Hankel行列式

Painlevé VI and Hankel determinants for the generalized Jacobi Weight

Dan Dai, Lun Zhang

摘要:

利用$α, β>0$,$t < 0 $和$γ\in\mathbb{R}$研究了$x\in[0,1]$的广义Jacobi权$(x-t)^γx^α(1-x)^β$的Hankel行列式.基于相应的一元正交多项式$P_n(x)$的梯形算子,证明了Painlevé VI系统的Hankel行列式的对数导数可用$τ$ -函数刻画.

英文摘要:

We study the Hankel determinant of the generalized Jacobi weight $(x-t)^γx^α(1-x)^β$ for $x\in[0,1]$ with $α, β>0$, $t < 0 $ and $γ\in\mathbb{R}$. Based on the ladder operators for the corresponding monic orthogonal polynomials $P_n(x)$, it is shown that the logarithmic derivative of Hankel determinant is characterized by a $τ$-function for the Painlevé VI system.
