Generating function for GL_n-invariant differential operators in the skew Capelli identity
摘要:
设Alt_n是复一般线性群GL_n通过$x \mapsto g x g^t$作用于其上的n阶交错复矩阵的向量空间。本文的目的是证明:对于Alt_n上多项式的乘法算子或导子为元素的矩阵,其Pfalan为GL_n不变的微分算子提供了一个母函数,这些微分算子在斜Capelli恒等式中起作用,系数为Hermite多项式.
英文摘要:
Let Alt_n be the vector space of all alternating n-by-n complex matrices, on which the complex general linear group GL_n acts by $x \mapsto g x g^t$. The aim of this paper is to show that Pfaffian of a certain matrix whose entries are multiplication operators or derivations acting on polynomials on Alt_n provides a generating function for the GL_n-invariant differential operators that play a role in the skew Capelli identity, with coefficients the Hermite polynomials.
