AI 中文摘要
我们在Kühn与Schneps的uri括号下,于交换不变交替双模构成的李代数$\boldsymbol{\frak{B}}$上,通过导子构造了一个$\boldsymbol{\frak{sl}_2}$作用。该李代数对应形式多重艾森斯坦级数的角色,正如Racinet的双洗牌李代数$\boldsymbol{\frak{dm}_0}$对应多重zeta值的角色。降算子的核$\boldsymbol{\frak{m}}$是一个李子代数,$\boldsymbol{\frak{B}}$是其在升算子作用下迭代的直和,这为$\boldsymbol{\frak{m}}$提供了Rankin-Cohen型算子。我们定义了$\boldsymbol{\frak{B}}$的一个李子代数$\boldsymbol{\frak{d}}$,并证明它同构于权1上添加额外元素的$\boldsymbol{\frak{dm}_0}$。
英文摘要
We construct an $\mathfrak{sl}_2$-action by derivations on the Lie algebra $\mathfrak B$ of swap invariant alternil bimoulds with the uri bracket of Kühn and Schneps. This Lie algebra plays the role for formal multiple Eisenstein series which Racinet's double shuffle Lie algebra $\mathfrak{dm}_0$ plays for multiple zeta values. The kernel $\mathfrak m$ of the lowering operator is a Lie subalgebra, $\mathfrak B$ is the direct sum of its iterates under the raising operator, and this gives Rankin-Cohen type operators on $\mathfrak m$. We define a Lie subalgebra $\mathfrak d$ of $\mathfrak B$ and show that it is isomorphic to $\mathfrak{dm}_0$ extended by an additional element in weight one.
