Abstract
We characterize the rearrangement invariant spaces for which there exists a non-constant fixed point, for the Hardy-Littlewood maximal operator (the case for the spaces Lp(Rn) was first considered in [7]). The main result that we prove is that the space Ln/(n-2),∞(R n) ∩ L∞(Rn) is minimal among those having this property.
