The asymptotic behavior of #n (d;) #n (d:) and Pn (x, d;) P n (x, d:) is studied. Here (#n (.))n are the leading coefficients of the orthonormal matrix polynomials Pn (x, .) with respect to the matrix measures d; and d: which are related by d;(u)= d:(u)+ k=1 Mk$(u&ck), where Mk are positive definite matrices, $ is the Dirac measure and ck lies outside the… (More)
In this paper we study a Jacobi block matrix and the behavior of the limit of its entries when a perturbation of its spectral matrix measure by the addition of a Dirac delta matrix measure is introduced. © 2001 Elsevier Science Inc. All rights reserved.
In this paper we give an overview of recent results on analytic properties of matrix orthonormal polynomials. We focus our attention on the distribution of their zeros as well as on the asymptotic behavior of such polynomials under some restrictions about the measure of orthogonality.
BACKGROUND Outpatient surgery is a major public health policy issue. It is controversial for total thyroidectomy, which raises the question of hemithyroidectomy. The present study assessed our experience in outpatient hemithyroidectomy. OBJECTIVES To evaluate the rates of postoperative hematoma and unscheduled hospital admission. MATERIAL AND METHODS A… (More)
