Abstract:A metric space M is said to have the fibered approximation property in dimension n (briefly, M ∈ FAP(n)) if for any ɛ > 0, m ≥ 0 and any map g: $ \mathbb{I} $ \mathbb{I} m × $ \mathbb{I} $ \mathbb{I} n M there exists a map g′: $ \mathbb{I} $ \mathbb{I} m × $ \mathbb{I} $ \mathbb{I} n M such that g′ is ɛ-homotopic to g and dim g′ ({z} × $ \mathbb{I} $ \mathbb{I} n ) ≤ n for all z ∈ $ \mathbb{I} $ \mathbb{I} m . The class of spaces having the FAP(n)-property is investigated in this paper. The main theorems are applied to obtain generalizations of some results due to Uspenskij 11] and Tuncali-Valov 10].
