基于一个部分布尔函数的几种分离性

Several Separations Based on a Partial Boolean Function

Kaspars Balodis

摘要:

我们示出了部分布尔函数$f$连同输入$x\in f^{-1}\left(*\right)$,使得$C_{\bar{0}}\left(f,x\right)$和$C_{\bar{1}}\left(f,x\right)$都至少是$C\left(f\right)^{2-o\left(1\right)}$。由于Ben-David,Göös,Jain和Kothari最近的结果,这个结果意味着查询和通信复杂性的其他几个分离。例如,它给出了一个函数$f$,其中$C(f)=Ω(deg^{2-o\left(1\right)}(f))$,其中$C$和$deg$表示证书复杂度和$f$的多项式次数。(This是对Kushilevitz和Nisan在1995年提出的$C(f)$和$deg(f)$之间的分离的第一次改进)。这一结果的其他影响是一个改进的分离之间的敏感性和多项式的程度,一个接近最优的下限conondeterministic通信复杂性的团与独立集问题和一个接近最优的下界的复杂性的Alon-Saks-Seymour问题的图论。

英文摘要:

We show a partial Boolean function $f$ together with an input $x\in f^{-1}\left(*\right)$ such that both $C_{\bar{0}}\left(f,x\right)$ and $C_{\bar{1}}\left(f,x\right)$ are at least $C\left(f\right)^{2-o\left(1\right)}$. Due to recent results by Ben-David, Göös, Jain, and Kothari, this result implies several other separations in query and communication complexity. For example, it gives a function $f$ with $C(f)=Ω(deg^{2-o\left(1\right)}(f))$ where $C$ and $deg$ denote certificate complexity and polynomial degree of $f$. (This is the first improvement over a separation between $C(f)$ and $deg(f)$ by Kushilevitz and Nisan in 1995.) Other implications of this result are an improved separation between sensitivity and polynomial degree, a near-optimal lower bound on conondeterministic communication complexity for Clique vs. Independent Set problem and a near-optimal lower bound on complexity of Alon--Saks--Seymour problem in graph theory.
