Abstract
In this paper, we construct the fuzzy S-act Hom S (μ A , ν B ), where μ A and ν B are two fuzzy S-acts. We also prove that Hom S (ξ p , −) preserves short exact sequence if and only if \(\xi_P\cong \coprod\nolimits_{i\in i}0_{Se_i},\) where e i ∈ E(S). Moreover, we give the definition of tensor product of two fuzzy S-acts and get some properties of tensor product.
