For a Lie comodule M of a Lie coalgebra C and the Lie algebra 𝔤 ( C , M ) (respectively, the group 𝔊 ( C , M ) ) of diagonal coderivations (respectively, Lie coalgebra automorphisms) of the semidirect sum C ⋉ M , we show that there is a representation of 𝔤 ( C , M ) (respectively, 𝔊 ( C , M ) ) on the second cohomology group H c 2 ( M , C ) , from which we construct obstruction classes of extensibility of pairs of coderivations (respectively Lie coalgebra automorphisms) and exact sequences of Wells type for abelian extensions of Lie coalgebras.

用于李余代数的阿贝尔扩展的 Wells 序列
对于李协模米 李代数的C 和李代数𝔤 ( C , 米 ) (分别地,该组𝔊 ( C , 米 ) ) 的半直接和的对角线代数(分别为李余代数自同构)C ⋉ 米 ,我们证明有一个表示𝔤 ( C , 米 ) (分别,𝔊 ( C , 米 ) ) 在第二上同调群上H C 2 ( 米 , C ) , 从中我们构造了对共导数(分别为李余代数自同构)的可扩展性的障碍类和用于李余代数的阿贝尔扩展的 Wells 类型的精确序列。
