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.
