• Abstract:
  We show under the assumption \bf {V} = \bf {L} that the {\rm Depth} of an ultraproduct of Boolean Algebras cannot jump over the {\rm Depth} of every component by more than one cardinal. This is done for every cardinal. We also get better results for singular cardinals with countable cofinality.
