Matrix Christoffel Functions

Constructive Approximation, 2004
This paper extends to a matrix setting many classical results from the scalar theory of orthogonal polynomials and Christoffel functions. Namely, the authors consider an \(N\times N\) matrix weight \(W\) (that is, a positive definite matrix of measures supported on \(\mathbb R\)), for which they define the sequence of matrix-valued orthonormal ...

Representation of Christoffel–Darboux formula for random matrix with external source and constrained eigenvalues

Reviews in Mathematical Physics
In this paper, we obtain a new representation of Christoffel–Darboux formula for random matrix with external source and constrained eigenvalues. In order to simplify the Christoffel–Darboux formula, we define two types of orthogonal polynomials, and find out the close relation between Riemann–Hilbert problem and orthogonal polynomials. Furthermore, the
