A NOTE ON THE QUADRATIC DECOMPOSITION OF A REVERSED POLYNOMIAL SEQUENCE

  • T. A. Mesquita

摘要

The reversed polynomial sequence of a given Appell sequence fulfils a differential-recurrence relation. This relation is analyzed from the viewpoint of the quadratic decomposition. Several differential identities fulfilled by the polynomial components of the quadratic decomposition are established. A generalized hypergeometric representation is also considered.
