Rankin-Cohen brackets of eigenforms
Abstract: This will be an (accessible) exposition of a result joint with Dominic Lanphier which characterizes when the Rankin-Cohen bracket of two eigenforms of full
level is an eigenform. We will show that this happens only for a finite number of cases, and identify every possibility. Our theorem generalizes a
theorem of Bill Duke dealing with products of eigenforms.
