There should be some note of what a $\sigma^*$ product is, otherwise it is not clear what the definition means for the average reader. Googling gives a different (but I suppose equivalent) definition with banach spaces.
We also do not have a counterexample to T220 (Eberlein compact => Corson compact), if anyone knows one, this would be very nice to have. (as right now Corson compact iff Eberlein compact for all spaces)
