摘要
For two weighted local Morrey spaces L-{x0}(p,phi)(Omega, u) and L-{x0}(p,phi)(Omega, v) we obtain general type sufficient conditions and necessary conditions imposed on the functions phi and psi and the weights u and v for the boundedness of the maximal operator from L-{x0}(p,phi)(Omega, u) to L-{x0}(p,phi)(Omega, v), with some "logarithmic gap" between the sufficient and necessary conditions. Both the conditions formally coincide if we omit a certain logarithmic factor in these conditions.
