Abstract

The Singular Cardinal Problem is the project to completely describe the behavior of the operation $\kappa\mapsto 2^\kappa$ when $\kappa$ is singular. In this talk I will give some background and present forcing notions that are used to obtain consistency results. Then I will go over some recent developments in the subject.
