We prove a quasi-polynomial lower bound on the size of bounded-depth Frege proofs of the pigeonhole principle PHPm n where m ´1 · 1 polylog nµn. This lower bound qualitatively ...

We present lower bounds on the computational power of an optical model of computation called the C2-CSM. We show that C2-CSM time is at least as powerful as sequential space, thus ...
