Abstract
AbstractWe consider the setting of manifolds with ends which are obtained by compact perturbation (gluing) of ends of the form $${\mathbb {R}}^{n_i}\times {\mathcal {M}}_i$$

. Interestingly, this is a closed-end condition in the considered setting. We prove that the corresponding maximal function is bounded in the same range except that it is only weak-type (1, 1) for $$p=1$$
