      Bergman Orthogonal Polynomials and the Grunsky Matrix 

      Beckermann, Bernhard; Stylianopoulos, Nikos (2018)
      By exploiting a link between Bergman orthogonal polynomials and the Grunsky matrix, probably first observed by Kühnau (Ann Acad Sci Math 10:313–329, 1985), we improve on some recent results on strong asymptotics of Bergman ...

      Perturbations of Christoffel–Darboux Kernels: Detection of Outliers 

      Beckermann, Bernhard; Putinar, Mihai; Saff, Edward B.; Stylianopoulos, Nikos (2020)
      Two central objects in constructive approximation, the Christoffel–Darboux kernel and the Christoffel function, encode ample information about the associated moment data and ultimately about the possible generating measures. ...
