Overtake and the recursive-line equality for second-order Zarankiewicz numbers
Chen Ouyang, Liqun Qi
We study two questions about the second-order Zarankiewicz numbers. The first is the recursive-line equality , known to hold in every computed case and conjec…
Unit Dual Quaternion Directed Graphs, Formation Control and General Weighted Directed Graphs
Liqun Qi, Chunfeng Cui, Chen Ouyang
We study the multi-agent formation control problem in a directed graph. The relative configurations are expressed by unit dual quaternions (UDQs). We call such a weighted directed…
An Orthogonal Equivalence Theorem for Third Order Tensors
Liqun Qi, Chen Ling, Jinejie Liu +1
In 2011, Kilmer and Martin proposed tensor singular value decomposition (T-SVD) for third order tensors. Since then, T-SVD has applications in low rank tensor approximation, tensor…
The first few unicyclic and bicyclic hypergraphs with larger spectral radii
Chen Ouyang, Liqun Qi, Xiying Yuan
A connected -uniform hypergraph with vertices and edges is called -cyclic if . For or , the hypergraph is simply called unicyclic or bicyclic.…
Some properties and applications of odd-colorable -hypergraphs
Xiying Yuan, Liqun Qi, Jiayu Shao +1
Let and be even. An -hypergraph on vertices is called odd-colorable if there exists a map such that for any edge $\{j_{1},j_{2}…
