A unified method for maximal truncated calderón–zygmund operators in general function spaces by sparse domination

In this note we give simple proofs of several results involving maximal truncated Calderon–Zygmund operators in the general setting of rearrangement-invariant quasi-Banach function spaces by sparse domination. Our techniques allow us to track the dependence of the constants in weighted norm inequalities; additionally, our results hold in ℝ n as well as in many spaces of homogeneous type.
