Abstract
We find the exact best possible range of those \(p >1\) for which any \(\varphi \in A_1({\mathbb {R}})\), with \(A_1\) constant equal to c, must also belong to \(L^p\). In this way, we provide an alternative proof of the corresponding result in Bojarski and Sbordone (Studia Math 101(2):155–163, 1992) and Nikolidakis (Ann Acad Scient Fenn Math 40:949–955, 2015).
