In this paper, we prove two local existence theorems, by using both the Picard method and the Schauder fixed-point theorem, for the following initial-value problem: $$g(\alpha )(x) = f(x,g(x))(almost all x\varepsilon [a,a + h])$$ with (A) $$g(\alpha - 1)(a) = b\Gamma (\alpha ),0 0; b is a real number, and under suitable conditions on the function f.
