Resumen de On the Brudnyi-Krugljak duality theory of spaces formed by the K-method of interpolation

Ron Kerman, Mario Milman, Gord Sinnamon

• The Brudnyi-Krugljak duality theory for the -method is elaborated for a class of parameters derived from rearrangement-invariant spaces. As examples, concrete expressions are given for the norms dual to certain interpolation spaces between two rearrangement-invariant spaces. These interpolation spaces are formed by the -method using parameters related to classical Lorentz spaces or Orlicz spaces.
