摘要
Matrix relations for orthogonal polynomials associated to a non-definite linear functional c are found. In addition, the reproducing kernels for the functional c are introduced and the coefficients of the Gaussian quadrature formulas for the functional c are also calculated by means of a procedure similar to that developed by Brezinski for definite functionals.
