Higher Braces Via Formal (Non)Commutative Geometry

Conference paper
Part of the Trends in Mathematics book series (TM)

Abstract

We translate the main result of [11] to the language of formal geometry. In this new setting we prove directly that the Koszul resp. Börjeson braces are pullbacks of linear vector fields over the formal automorphism \(\varphi(a)=\mathrm{exp}(a)-1\) in the Koszul, resp. \(\varphi(a)=a(1-a)^{-1}\) in the Börjeson case. We then argue that both braces are versions of the same object, once materialized in the world of formal commutative geometry, once in the noncommutative one.
