Published in 2021 at "Mathematics in Computer Science"

DOI: 10.1007/s11786-020-00468-y

Abstract: We apply a symbolic approach of the general quadratic decomposition of polynomial sequences—presented in a previous article referenced herein—to polynomial sequences fulfilling specific orthogonal conditions towards two given functionals $$u_{0},u_{1}$$ u 0 , u 1… read more here.

DOI: 10.1080/10652469.2020.1763984

Abstract: ABSTRACT A polynomial sequence is symmetric, or self-dual, if for all . In this paper, we give the characterization of the exponential symmetric Sheffer sequences with weight sequences, and show that all the symmetric Sheffer… read more here.

Published in 2024 at "Filomat"

DOI: 10.2298/fil2404279b

Abstract: In [9] I. Lamiri and M. Ouni state some characterization theorems for d-orthogonal polynomials of Hermite, Gould-Hopper and Charlier type polynomials. In [3] Y. Ben Cheikh I. Lamiri and M.Ouni give a characterization theorem for… read more here.
