Title
THE TREE PROPERTY AT THE TWO IMMEDIATE SUCCESSORS OF A SINGULAR CARDINAL
Abstract
We present an alternative proof that from large cardinals, we can force the tree property at kappa(+) and kappa(++) simultaneously for a singular strong limit cardinal kappa. The advantage of our method is that the proof of the tree property at the double successor is simpler than in the existing literature. This new approach also works to establish the result for kappa = N-omega 2.
