Pre- and Post-Lie Algebras: The Algebro-Geometric View. (arXiv:1704.06171v1 [math.AG])
来源于:arXiv
We relate composition and substitution in pre- and post-Lie algebras to
algebraic geometry. The Connes-Kreimer Hopf algebras, and MKW Hopf algebras are
then coordinate rings of the infinite-dimensional affine varieties consisting
of series of trees, resp.\ Lie series of ordered trees. Furthermore we describe
the Hopf algebras which are coordinate rings of the automorphism groups of
these varieties, which govern the substitution law in pre- and post-Lie
algebras. 查看全文>>
