A class of inequalities relating degrees of adjacent nodes to the average degree in edge-weighted uniform hypergraphs

International Journal of Mathematics and Mathematical Sciences, 2005
In 1986, Johnson and Perry proved a class of inequalities for uniform hypergraphs which included the following: for any such hypergraph, the geometric mean over the hyperedges of the geometric means of the degrees of the nodes on the hyperedge is no less

Hypergraph: A Unified and Uniform Definition with Application to Chemical Hypergraph and More

The conventional definition of hypergraph has two major issues: (1) there is not a standard definition of directed hypergraph and (2) there is not a formal definition of nested hypergraph.
