Query: The Signless Laplacian Matrix of Hypergraphs   In this paper we define signless Laplacian matrix of a hypergraph and obtain
structural properties from its eigenvalues. We generalize several known results
for graphs, relating the spectrum of this matrix with structural parameters of
the hypergraph such as the maximum degree, diameter and the chromatic number.
In addition, we characterize the complete signless Laplacian spectrum for the
class of the power hypergraphs from the spectrum of its base hypergraph.
