针对Lovász与Szegedy提出的非常数有限可强制核存在性问题,构造了满足特定范围取值的显式实解析核,并证明存在与参数无关的图族可强制该核。
AI 中文摘要
Lovász与Szegedy提出是否存在非常数连续甚至光滑的有限可强制核的问题。对所有0<λ≤1/128,我们构造了取值于(1/4,7/8)的显式非常数实解析核W_λ,存在与λ无关的单个有限简单图族,可在[0,1]^2上所有有界对称实值核中强制每个W_λ。
英文摘要
Lovász and Szegedy asked whether a nonconstant continuous, or even smooth, finitely forcible kernel exists. For every $0<λ\leq1/128$, we construct an explicit nonconstant real-analytic kernel $W_λ$ taking values in $(1/4,7/8)$. A single finite family of simple graphs, independent of $λ$, forces every $W_λ$ among all bounded symmetric real-valued kernels on $[0,1]^2$.
