報告摘要: Recently the notion of post-Hopf algebra was introduced, with the universal enveloping algebra of a post-Lie algebra as the prototype. Any cocommutative post-Hopf algebra gives rise to a sub-adjacent Hopf algebra, and then produces interacting structures such as relative Rota-Baxter operator, matched pair and Hopf brace. Just a few weeks ago, Sciandra proposed Yetter-Drinfeld post-Hopf algebra, as a natural generalization of post-Hopf algebra in the non-cocommutative setting, and most remarkably it also provides a sub-adjacent structure. Correspondingly, the concepts of Yetter-Drinfeld relative Rota-Baxter operator and Yetter-Drinfeld Hopf brace can be studied. In this talk, I intend to review Sciandra's work, and give some problems to concern.
