摘要:
借助模糊软集的概念,在李代数上定义了模糊软李子代数和模糊软李子代数之间的模糊软同态, 对它们的并、交与和的性质进行了研究,证明了:设L是域F上的李代数,若(f,A)和(g,B)是L上的模糊软李子代数,则(f,A)∩(g,B)和(f,A)∧(g,B)仍然是L上的模糊软李子代数,但(f,A)∪(g,B)不一定是L上的模糊软李子代数;若(f,A)k是L上的一族预模糊软李理想,则∪k∈K(f,A)k和∩k∈K(f,A)k仍然是L上的预模糊软李理想.证明了模糊软李子代数的同态逆像定理,给出一个反例以说明模糊软李子代数在同态像下不一定是模糊软李子代数.

Abstract:
In terms of fuzzy soft sets, the notions and fuzzy soft homomorphism of fuzzy soft Lie subalgebras in Lie algebras are defined, and some properties, such as union, intersection and AND, are studied and the following conclusions are proved. If L is a Lie algebra over a field F, (f,A) and (g,B) are fuzzy soft Lie subalgebras on L,then (f,A)∩(g,B) and (f,A)∧(g,B) are still fuzzy soft Lie subalgebras on L,but (f,A)∪(g,B) need not to be fuzzy soft Lie subalgebra on L;if (f,A)k is a family of pre-fuzzy soft Lie ideals on L,then ∪k∈K(f,A)k and ∩k∈K(f,A)k are still pre-fuzzy soft Lie ideals on L.A theorem on fuzzy soft homomorphic pre-image of fuzzy soft Lie subalgebra is proved and a counterexample is given in order to show the image of a fuzzy soft Lie subalgebra under a homomorphism of fuzzy soft Lie subalgebra need not to be a fuzzy soft Lie subalgebra.
