Cohen \(\cal M11\): Forti/Honsell Model | Historical notes
Description: Using a model of \(ZF + V = L\) for the ground model, the authors construct a generic extension, \(\cal M\), using Easton forcing which adds \(\kappa\) generic subsets to each regular cardinal \(\kappa\)
Parameter(s): This model does not depend on parameters
