Derived operations satisfy standard identities

Rings and Algebras 2025-11-25 v2

Abstract

A derived operation is a bilinear operation on a commutative associative algebra AA defined intrinsically out of its product and several derivations of the product. We show that operators of left (or right) multiplications of a derived operation always satisfy a "standard identity" of certain order. In particular, it implies that each Rankin-Cohen bracket of modular forms, as well as each higher bracket of Kontsevich's universal deformation quantization formula for Poisson structures on Rn\mathbb{R}^n, satisfies standard identities.
