Post-Lie Algebras and Isospectral Flows
Published 10 May 2015 in math.RA, math-ph, and math.MP | (1505.02436v3)
Abstract: In this paper we explore the Lie enveloping algebra of a post-Lie algebra derived from a classical $R$-matrix. An explicit exponential solution of the corresponding Lie bracket flow is presented. It is based on the solution of a post-Lie Magnus-type differential equation.
