A spectral method to incidence balance of oriented hypergraphs and induced signed hypergraphs
Yi Wang, Le Wang, Yi-Zheng Fan
An oriented hypergraph is a hypergraph together with an incidence orientation such that each edge-vertex incidence is given a label of or . An oriented hypergraph is calle…
On the largest eigenvalue of a mixed graph with partial orientation
Bo-Jun Yuan, Yi Wang, Yi-Zheng Fan
Let be a connected graph and let be a spanning tree of . A partial orientation of respect to is an orientation of the edges of except those edges of ,…
Minimal non-odd-transversal hypergraphs and minimal non-odd-bipartite hypergraphs
Yi-Zheng Fan, Yi Wang, Jiang-Chao Wan
Among all uniform hypergraphs with even uniformity, the odd-transversal or odd-bipartite hypergraphs are more close to bipartite simple graphs from the viewpoint of both structure…
The least H-eigenvalue of adjacency tensor of hypergraphs with cut vertices
Yi-Zheng Fan, Zhu Zhu, Yi Wang
Let be a connected hypergraph with even uniformity, which contains cut vertices. Then is the coalescence of two nontrivial connected sub-hypergraphs (called branches) at a…
