Abstract We present a generalized comparison identity for a two point boundary value problem, and we apply it to show the uniqueness of positive radial solutions of { Δ u ( x ) + f ( u ( x ) ) = 0 in A a , b , u ( x ) = 0 on ∂ A a , b , where n ∈ N with n ≥ 2 , 0 a b ∞ , A a , b = { x ∈ R N : a | x | b } and f ∈ C 1 [ 0 , ∞ ) is a superlinear function.
