On $PP$ and derandomization

$PP\subseteq P/poly\implies PP=\Sigma_2\cap\Pi_2$ and $EXP\subseteq P/Poly\implies EXP=PP$ $=CH=MA$. If $PP\subseteq P/poly$ then can $PP=\Sigma_2\cap\Pi_2=MA$ hold? Are there difficulties showing t …

Interlaced uniform versus non-uniform hierarchy

Denote $\mathsf{uniform}$ class with prefix $\mathsf{u}$ and $\mathsf{non}$-$\mathsf{uniform}$ class with prefix $\mathsf{nu}$. In following some non-trivial standard notion of uniformity (like $\mat …

What do stronger circuit lower bounds give in terms of derandomization?

We have $EXP\not\subseteq P/poly\implies BPP\subseteq io-DTIME(2^{n^\epsilon})$ at every $\epsilon>0$. This is essentially $DTIME(2^{O(n)})\not\subseteq P/poly\implies BPP\subseteq io-DTIME(2^{n^\eps …
