Query: On relations between weak and strong type inequalities for maximal
  operators on non-doubling metric measure spaces   In this article we characterize all possible cases that may occur in the
relations between the sets of $p$ for which weak type $(p,p)$ and strong type
$(p,p)$ inequalities for the Hardy--Littlewood maximal operators, both centered
and non-centered, hold in the context of general metric measure spaces.
