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.

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.
