A locally integrable function is a function which is integrable on every compact subset of its domain of definition.
For any locally integrable function f and z [member of] H, it follows that
Let w be a weight (i.e., a nonnegative, locally integrable function) on [R.sup.d] and let M stand for the usual Hardy-Littlewood maximal operator.

Let p: [OMEGA] [right arrow] ]1, +[infinity]] be a locally integrable function such that 1 < [p.sup.-] = [inf.sub.x [member of] [OMEGA]]p(x) and [p.sup.+] = [sup.sub.x [member of] [OMEGA]]p(x) [less than or equal to] [infinity].
Let g be a nonnegative, locally integrable function such that [[intergral].sup.t] g [not equal to] 0, and the functions q and r continuous functions with r > 0.

We say w a weight if w is a non-negative and locally integrable function. For a subset E [subset] [R.sup.n], [[chi].sub.E] means the characteristic function of E and [absolute value of E] denotes the volume of E.
By a weight, we shall mean a locally integrable function v on [R.sup.n] such that v(x) > 0 for a.e.
