Abstract Let μ be a non-negative Borel measure on ℝd which only satisfies some growth condition, we study two-weight norm inequalities for fractional maximal functions associated to such μ. A necessary and sufficient condition for the maximal operator to be bounded from LP(v) into weak Lq(u) (1 ≤ p ≤ q < ∞) is given. Furthermore, by using certain Orlicz norm, a strong type inequality is obtained. 2010 Mathematics Subject Classification: 42B25. Key words and phrases: Non-homogeneous spaces, Fractional maximal operators, Muckenhoupt weights.
