A Lower Bound for Polynomial Calculus with Extension Rule
arXiv - CS - Computational Complexity Pub Date : 2020-10-12 , DOI: arxiv-2010.05660
Yaroslav Alekseev

In this paper we study an extension of the Polynomial Calculus proof system where we can introduce new variables and take a square root. We prove that an instance of the subset-sum principle, the binary value principle, requires refutations of exponential bit size over rationals in this system. Part and Tzameret proved an exponential lower bound on the size of Res-Lin (Resolution over linear equations) refutations of the binary value principle. We show that our system p-simulates Res-Lin and thus we get an alternative exponential lower bound for the size of Res-Lin refutations of the binary value principle.

具有扩展规则的多项式微积分的下界

在本文中,我们研究了多项式微积分证明系统的扩展,我们可以在其中引入新变量并取平方根。我们证明了子集和原理的一个实例,即二进制值原理,需要在该系统中对有理数的指数位大小进行反驳。Part 和 Tzameret 证明了 Res-Lin(线性方程的分辨率)反驳二进制值原理的大小的指数下界。我们展示了我们的系统 p 模拟了 Res-Lin,因此我们得到了 Res-Lin 反驳二进制值原理的大小的替代指数下限。
