Query: Singular measures and convolution operators   We show that in the study of certain convolution operators, functions can be
replaced by measures without changing the size of the constants appearing in
weak type (1,1) inequalities. As an application, we prove that the best
constants for the centered Hardy-Littlewood maximal operator associated to
parallelotopes do not decrease with the dimension.
