Hi, following is the question I have been thinking about for a while -
Is $\displaystyle \mathcal{B}(l_\infty \times l_\infty) = \sigma(\mathcal{B}(l_\infty) \times \mathcal{B}(l_\infty))?$
Can anyone help me on this? Thanks a lot.

Hi girdav, I read the link again. The doubt I have is the theorems says that for spaces with cardinality greater than 'c' we have the non-equality. But from what I understood, he doesn't prove the equality for all spaces with cardinality equal to 'c'. Am I missing something?
