摘要: 首先, 给出预李代数作用的定义及交叉模的定义, 并研究交叉模的相关性质; 其次, 利用交叉模的定义和预李代数的半直积给出预李代数交叉模的同构类与cat1-预李代数的同构类是等价的结果; 最后, 给出交叉模的同态和同态的同伦构成一个群胚结构.

Abstract: Firstly, we gave the definitions of the action and the crossed module of pre-Lie algebras, and studied the related properties of the 
crossed module. Secondly, a result was given that the isomorphism class of crossed modules of pre-Lie algebra was equivatent to that of cat1-pre-Lie algebras by using the definition of the crossed modules and semidirect product of pre-Lie algebras. Finally, we showed that the homomorphisms and their homotopies of crossed module formed a groupoid structure.

Key words: pre-Lie algebra, crossed module, action, homomorphism, groupoid
