Asymptotic formulas for the frame coefficients generated by Laguerre and Hermite type polynomials

R. Khabibouline, J. Prestin

Abstract

Polynomial frames based on orthogonal decompositions with respect to weights of Laguerre and Hermite type are considered. Asymptotic formulas for the coefficients from expansions on such frames are presented. The ability to detect singularities of all order is studied in detail.
