An Easy-Sounding Problem Yields Numbers Too Big for Our Universe
Most researchers thought Lipton had cooked up the most complex possible vector addition systems, meaning he’d raised the lower bound as high as it could go. The only thing missing, in that case, would be an upper bound to go with it — that is, a proof that there could be no system in which… Continue reading An Easy-Sounding Problem Yields Numbers Too Big for Our Universe
