Reps of the lowering / destruction / annihilation operator for binomial Sheffer polynomial sequences
Just posted a belated response concerning these reps to the question “Trying to characterize an ;umbral shift‘” on Math Stack Exchange posted by the creator of the YouTube video The Shadowy World of Umbral Calculus. The analysis includes a presentation … Continue reading →
