Transmutations from the Covariant Transform on the Heisenberg Group and an Extended Umbral Principle
Published 23 May 2023 in math.AP, math.CO, and math.FA | (2305.14227v2)
Abstract: We discuss several seemingly assorted objects: the umbral calculus, generalised translations and associated transmutations, symbolic calculus of operators. The common framework for them is representations of the Weyl algebra of the Heisenberg group by ladder operators. Transporting various properties between different implementations we review some classic results and new opportunities.
