Lexicographical ordering by spectral moments of bicyclic hypergraphs
Hong Zhou, Changjiang Bu
For bicyclic hypergraphs, ordering by spectral moment (-order) is investigated in this paper. We give the first and last hypergraphs in an -order of linear bicyclic uniform h…

Extremal Zagreb indices of bicyclic hypergraphs
Hong Zhou, Changjiang Bu
The Zagreb index of a hypergraph is defined as the sum of the squares of the degrees of its vertices. A connected -uniform hypergraph with vertices and edges is called b…
