- ItemOn the extreme eigenvalues of certain matrices of non-standard inner products of Hermite polynomials(Elsevier, 2018-01-01) Plešinger Martin; Pultarová IvanaWe study Hermite orthogonal polynomials and Gram matrices of their non-standard inner products. The weight function of the non-standard inner product is obtained from the Gauss probability density function by its horizontal shift by a real parameter. We are interested in the spectral properties of these matrices and some of their modifications. We show how the largest and smallest eigenvalues of the matrices depend on the parameter.
