Determine whether the adjacency matrix encodes hypergraph colorings

Determine whether the characteristic adjacency matrix A_H of a hypergraph provides information about colorings of that hypergraph.

Background

The paper establishes that its characteristic adjacency matrix fully characterizes the underlying hypergraph up to isomorphism and derives several spectral and graph-theoretic properties. It leaves unresolved whether this matrix also captures useful information about hypergraph colorings, making the relationship between the matrix representation and coloring structure an explicit open direction.
