Sh:1257

• Shelah, S. Homogeneous forcing. Preprint.
• Abstract:
  Assume \kappa = \aleph_0 or \kappa = \kappa^{<\kappa} > \aleph_0, usually an inaccessible.

  We shall deal with iterated forcings preserving {}^{\kappa>}Ord and not collapsing cardinals along a linear order. The aim is to have homogeneous ones, so that for some natural ideals on {}^\kappa2, we get a model of ZF + DC_\kappa\ + “modulo this ideal, every set is equivalent to a \kappa-Borel one."

  The main application is improving the consistency result of Kellner and Shelah [Sh:859], and Horowitz and Shelah [Sh:1067] on saccharinity.
