We apply the techniques of monotone and relative rearrangements to the nonrearrangement invariant spaces Lp(⋅)(Ω) with variable exponent. In particular, we show that the maps [Formula: see text] and [Formula: see text] are locally ϕ-Hölderian (u∗(resp. p∗) is the decreasing (resp. increasing) rearrangement of u (resp. p)). The pointwise relations for the relative rearrangement are applied to derive the Sobolev embedding with eventually discontinuous exponents.
