报告摘要：
This project introduces Rota-Baxter Lie 2-algebras as the categorification of Rota-Baxter Lie algebras. We prove that the category of Rota-Baxter Lie 2-algebras is equivalent to the category of 2-term Rota-Baxter L-infinity-algebras. We further establish a one-to-one correspondence between strict 2-term Rota-Baxter L-infinity-algebras and crossed modules of Rota-Baxter Lie algebras. As an application of such crossed modules, we provide explicit constructions for crossed modules of pre-Lie algebras and Lie algebras. This is a joint work with Jiefeng Liu.
