BKP层次与Pfronan点过程

BKP hierarchy and Pfaffian point process

Zhi-Lan Wang, Shi-Hao Li

摘要:

受Okounkov [ \emph{Selecta Mathematica},7(1):57- 81,2001]将KP族与行列式点过程联系起来的启发,本文建立了BKP族与Pfuman点过程之间的关系.证明了严格分拆上的移位Schur测度的关联函数可以表示为一个反对称矩阵核的Pfronan,其元素是中性费米子的某些真空期望.我们进一步证明了BKP族的矩阵积分解也能诱导出一定的Pfavian点过程。

英文摘要:

Inspired by Okounkov's work [\emph{Selecta Mathematica}, 7(1):57--81, 2001] which relates KP hierarchy to determinant point process, we establish a relationship between BKP hierarchy and Pfaffian point process. We prove that the correlation function of the shifted Schur measures on strict partitions can be expressed as a Pfaffian of skew symmetric matrix kernel, whose elememts are certain vacuum expectations of neutral fermions. We further show that the matrix integrals solution of BKP hierarchy can also induce a certain Pfaffian point process.
