Modular linear differential operators and generalized Rankin-Cohen brackets
Modular linear differential operators and generalized Rankin-Cohen brackets
The aim of this paper is to give expressions for modular linear differential operators (MLDOs) of any order. In particular, we show that they can all be described in terms of Rankin-Cohen brackets and a modified Rankin-Cohen bracket found by Kaneko and Koike. We also give more uniform descriptions of …
