On the Christoffel-Darboux kernel for random Hermitian matrices with external source
摘要:
Bleher和Kuijlaars以及Daems和Kuijlaars证明了具有外部源的酉系综的随机矩阵的特征值的相关函数可以用多个正交多项式的Christoffel-Darboux核来表示。我们得到了一个表示的Christoffel-Darboux内核在通常的正交多项式。
英文摘要:
Bleher and Kuijlaars, and Daems and Kuijlaars showed that the correlation functions of the eigenvalues of a random matrix from unitary ensemble with external source can be expressed in terms of the Christoffel-Darboux kernel for multiple orthogonal polynomials. We obtain a representation of this Christoffel-Darboux kernel in terms of the usual orthogonal polynomials.
