一句话:关注 AC0[p]-Frege 超多项式下界这一开放问题,讨论常数深度代数证明系统的能力与已有子系统下界。
本文属于证明复杂度研究,关注 AC0[p]-Frege 证明系统的超多项式下界这一重要开放问题。AC0[p]-Frege 是带素数模计数门的常数深度电路类 AC0[p] 对应的证明系统。尽管 AC0[p] 电路的下界已存在约三十年,AC0[p]-Frege 本身仍没有显著下界。对于该系统的若干子系统,包括 Nullstellensatz、Polynomial Calculus 和 SOS,已有大量次数下界,但如何将这些结果推广到 AC0[p]-Frege 仍无进展。论文围绕常数深度代数证明的意外能力展开,指出代数证明子系统与完整 AC0[p]-Frege 下界之间的差距。摘要未给出具体新证明方法或评估细节。
A major open problem in proof complexity is to prove superpolynomial lower bounds for AC0[p]-Frege proofs. This system is the analog of AC0 [p], the class of bounded depth circuits with prime modular counting gates. Despite strong lower bounds for this class dating back thirty years ([28, 30]), there are no significant lower bounds for AC0 [p]-Frege. Significant and extensive degree lower bounds have been obtained for a variety of subsystems of AC0[p]-Frege, including Nullstellensatz ([3]), Polynomial Calculus ([9]), and SOS ([14]). However to date there has been no progress on AC0 [p]-Frege lower bounds.
