\paper On estimates of non-increasing rearrangement of generalized fractional maximal function
\paperinfo We give a sharp pointwise estimates of the non-increasing rearrangement
of the generalized fractional maximal function (MΦf)(x) via an expression involving
the non-increasing rearrangement of f. It is shown that the obtained estimate is more
sharp than the inequality which is followed from the estimate for the generalized Riesz
potential.
