AI总结:

本文研究了李2群上的相对罗塔-巴克斯算子及其诱导的因子分解定理,并探讨了其与交叉同态之间的关系。

摘要:

在李2群上引入相对罗塔-巴克斯算子,作为其底层李群上的相对罗塔-巴克斯算子对,同时也是一个李群胚的态射。此类算子诱导出李2群的因子分解定理,并导致杨-巴克斯方程的范畴解。我们进一步定义了李群交叉模上的相对罗塔-巴克斯算子。众所周知的李2群与交叉模之间的一一对应关系被扩展为这两种结构上相应相对罗塔-巴克斯算子之间的等价关系。最后,作为相对罗塔-巴克斯算子的正式逆运算,研究了李2群上的交叉同态。

英文摘要:

A relative Rota-Baxter operator on Lie 2-groups is introduced as a pair of relative Rota-Baxter operators on the underlying Lie groups which is also a Lie groupoid morphism. Such an operator induces a factorization theorem for Lie 2-groups and gives rise to a categorical solution of the Yang-Baxter equation. We further define relative Rota-Baxter operators on Lie group crossed modules. The well-known one-to-one correspondence between Lie 2-groups and crossed modules is extended to an equivalence between the respective relative Rota-Baxter operators on these two structures. Finally, as the formal inverse of relative Rota-Baxter operators, crossed homomorphisms on Lie 2-groups are also studied.
