本文证明了每个3-均匀超图可划分为k部分,每部分边数至多m/k^3+O_k(m^{2/3}),解决了Scott提出的误差项猜想。

设 $k\ge2$ 为固定整数。Bollobás 和 Scott 证明了每个具有 $m$ 条边的 3-均匀超图都允许将其顶点集划分为 $k$ 个部分,使得每个部分至多跨越 $m/k^3+O_k(m^{6/7})$ 条边。Scott 后来提出误差项应为 $O_k(m^{2/3})$。在本文中,我们证明每个具有 $m$ 条边的 3-均匀超图都允许划分为 $k$ 个部分,使得每个部分至多跨越 $m/k^3+O_k(m^{2/3})$ 条边,从而确立了所提出的误差项。
英文摘要
Let $k\ge2$ be a fixed integer. Bollobás and Scott proved that every $3$-uniform hypergraph with $m$ edges admits a partition of its vertex set into $k$ parts such that each part spans at most $m/k^3+O_k(m^{6/7})$ edges. Scott later suggested that the error term should be $O_k(m^{2/3})$. In this paper, we show that every $3$-uniform hypergraph with $m$ edges admits a partition into $k$ parts such that each part spans at most $m/k^3+O_k(m^{2/3})$ edges, thereby establishing the proposed error term.
