摘要:

对于 Hamming 图 $H(n,q)$,其中 $q$ 是恒定素数幂而 $n$ 增长,我们构造了无非本质自变量的完美着色,使 $n$ 指数依赖于商矩阵的非对角部分。特别地,我们构造了不平衡的 Boolean($q=2$)函数,使其本质自变量的数量指数依赖于函数的次数。

英文摘要:

For the Hamming graph $H(n,q)$, where $q$ is a constant prime power and $n$ grows, we construct perfect colorings without non-essential arguments such that $n$ depends exponentially on the off-diagonal part of the quotient matrix. In particular, we construct unbalanced functions (in the case $q=2$, Boolean functions) such that the number of essential arguments depends exponentially on the degree of the function. Another framing of the main construction is that it gives a sequence of very regular functions (perfect colorings) whose number of essential arguments grows exponentially with respect to sensitivity. A classical result that connects sensitivity with the number of essential arguments in the binary ($q=2$) case is the Simon--Wegener theorem. We prove an analog of this theorem for an arbitrary $q$. Keywords: boolean functions, perfect colorings, equitable partitions, degree, sensitivity, essential arguments
