Query: Spectra of Complex Unit Hypergraphs   A complex unit hypergraph is a hypergraph where each vertex-edge incidence is
given a complex unit label. We define the adjacency, incidence, Kirchoff
Laplacian and normalized Laplacian of a complex unit hypergraph and study each
of them. Eigenvalue bounds for the adjacency, Kirchoff Laplacian and normalized
Laplacian are also found. Complex unit hypergraphs naturally generalize several
hypergraphic structures such as oriented hypergraphs, where vertex-edge
incidences are labelled as either $+1$ or $-1$, as well as ordinary
hypergraphs. Complex unit hypergraphs also generalize their graphic analogues,
which are complex unit gain graphs, signed graphs, and ordinary graphs.
