Abstract

It is well known that if the Hardy–Littlewood maximal operator is bounded in the variable exponent Lebesgue space Lp()[0;1], then p()BMO1/log. On the other hand, there exists an exponent p()BMO1/log, 1<p-p+<, such that the Hardy–Littlewood maximal operator is not bounded in Lp()[0;1]. But for any exponent p()BMO1/log, 1<p-p+<, there exists a constant c>0 such that the Hardy–Littlewood maximal operator is bounded in Lp()+c[0;1]. In this paper, we construct an exponent p(), 1<p-p+<, 1/p()BLO1/log such that the Hardy–Littlewood maximal operator is not bounded in Lp()[0;1].
