In this paper, we consider the existence of positive solutions for second-order differential equations with deviating arguments and nonlocal boundary conditions. By the fixed point theorem due to Avery and Peterson, we provide sufficient conditions under which such boundary value problems have at least three positive solutions. We discuss our problem both for delayed and advanced arguments α and also in the case when α(t)=t, t∈[0,1]. In all cases, the argument β can change the character on [0,1], see problem (1). It means that β can be delayed in some set J¯⊂[0,1] and advanced in [0,1]∖J¯. An example is added to illustrate the results.
