ture (joint with Monroe Eskew)\nAbstract: \nI will review some consistency
results related to Chang's Conjecture (CC). \nFirst I will discuss some c
lassical results of deriving instances of CC from huge cardinals and the n
ew results for getting instances of CC from supercompact cardinals\, and p
resent some open problems. \nThen\, I will review the consistency proof of
some versions of the Global Chang's Conjecture - which is the consistency
of the occurrence many instances of CC simultaneously. \nWe will aim to s
how the consistency of the statement: (\mu^+\,\mu) -->> (\nu^+\,\nu) for a
ll regular \mu and all \nu < \mu\, starting from a huge cardinal. In order
to prove this we will start with the easier task in which $\mu$ is assume
d to be regular. In order to get the stronger result\, we will force with
Radin forcing over a model in which many instances of CC hold.\n\n Export
