Jul 5, 2021 at 13:29 comment added mike @YuvalFilmus thanks for the answer but I think this part of your answer "Since TQBF is PSPACE-complete, there is some logspace reduction from L to TQBF" is a bit misleading and it needs a change. please look at the cs.stackexchange.com/questions/90527/… .
Dec 4, 2020 at 23:33 comment added Macrophage Ah, sorry...I see it now, it's bounded by Savitch's theorem.
Dec 4, 2020 at 23:29 comment added Macrophage More specifically, I'm wondering how we can put an upper bound on the size of the output of the logspace reduction to TQBF.
Dec 4, 2020 at 23:27 comment added Macrophage Thanks, I just tried to derive that TQBF is indeed complete using logspace reduction. But I still have some question about what "blowing up" instances mean in your answer. I'm trying to prove by contradiction and somehow use the padding argument.

Dec 16, 2013 at 20:44 comment added InsigMath Hey @YuvalFilmus if you are interested in the solution to this problem, here is another version of this problem with exponent $n^{\frac{1}{4}}$ as solved by Professor Cook - cs.toronto.edu/~sacook/csc463h/problems/solutions4.pdf it's question 4
