• TITLE: Matrices Associated with Moving Least-Squares Approximation and Corresponding Inequalities

  AUTHORS: Svetoslav Nenov, Tsvetelin Tsvetkov

  KEYWORDS: Moving Least-Squares Approximation, Singular-Values

  JOURNAL NAME: Advances in Pure Mathematics, Vol.5 No.14, December 28, 2015

  ABSTRACT: In this article, some properties of matrices of moving least-squares approximation have been proven. The used technique is based on known inequalities for singular-values of matrices. Some inequalities for the norm of coefficients-vector of the linear approximation have been proven.
