引入了弱李2-双代数的概念。广义地说,弱Lie 2-双代数是向量空间及其对偶上的一对相容的2-项L∞-代数结构。兼容性条件用大括号来描述。证明了(严格)李2-双代数与李双代数的交叉模一一对应。
We introduce the notion of weak Lie 2-bialgebra. Roughly, a weak Lie 2-bialgebra is a pair of compatible 2-term L∞-algebra structures on a vector space and its dual. The compatibility condition is described in terms of the big bracket. We prove that (strict) Lie 2-bialgebras are in one–one correspondence with crossed modules of Lie bialgebras.
