DESCRIPTION:Title: <a href="https://researchseminars.org/talk/HAeS/3/">Wei
 ghted Morrey spaces</a>\nby Javier Duoandikoetxea (Euskal Herriko Uniberts
 itatea) as part of Harmonic analysis e-seminars\n\n\nAbstract\nThis talk i
 s an account of my work on Morrey spaces with Marcel \nRosenthal in recent
  years.\n\nThere are several definitions for weighted Morrey spaces. We ob
 tain \nboundedness results in all of them for operators satisfying the \na
 ssumptions of the usual extrapolation theorem\, that is\, we get \nweighte
 d Morrey estimates from weighted Lebesgue  estimates with $A_p$ \nweights.
  The results can be applied to a variety of operators and \ntogether with 
 the norm estimates\, our technique also provides the \ndefinition of the o
 perator by embedding.\n\nRecently we obtained results for a more general c
 lass of weighted \nMorrey spaces from an extension of the usual Muckenhoup
 t condition to \nthe Morrey setting\, involving the Khöthe dual of the sp
 ace. In some \ncases the conditions characterize the weighted inequalities
  of maximal \noperators.\n
