Abstract
Some orthogonal polynomial systems are mapped onto each other by the Fourier transform. In this paper, based on generalized Laguerre polynomials, we introduce a new sequence of biorthogonal hypergeometric polynomials and obtain its orthogonality relation explicitly. In this sense, we also recall some similar results available in the literature as the sequence introduced in this work is the last one for classical cases.
