Abstract
In this article we define and investigate a local Hardy–Littlewood maximal operator in Euclidean spaces. It is proved that this operator satisfies weighted L p, p > 1, and weighted weak type (1,1) estimates with weight function \({w \in A^p_{\rm{loc}}}\), the class of local A p weights which is larger than the Muckenhoupt A p class. Also, the condition \({w \in A^p_{\rm{loc}}}\) turns out to be necessary for the weighted weak type (p,p), p ≥ 1, inequality to hold.
