Post-Lie Algebras and Isospectral Flows

Name: Work Video:
Duration: 3 min 30 s
Description: 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.
