1965年,Motzkin和Straus在图的拉格朗日全局最大值G的标准单纯形和G的团数之间建立了显着的联系。在本文中,我们提供了 Motzkin-Straus 定理 tok 一致超图(k 图)的推广。具体来说,给定 ak-graphG,我们展示了一系列(参数化)齐次多项式,其局部(全局)极小值与 G 的最大(最大)派系一一对应。
In 1965, Motzkin and Straus established a remarkable connection between the global maxima of the Lagrangian of a graphGover the standard simplex and the clique number ofG. In this paper, we provide a generalization of the Motzkin–Straus theorem tok-uniform hypergraphs (k-graphs). Specifically, given ak-graphG, we exhibit a family of (parameterized) homogeneous polynomials whose local (global) minimizers are shown to be in one-to-one correspondence with maximal (maximum) cliques ofG.
