Spectral bounds for distance coloring and packing parameters of graphs via semidefinite programming
Aida Abiad, Yue Yang, Jiang Zhou
Using methods from spectral graph theory and semidefinite programming, we obtain sharp spectral bounds for several graph parameters related to distance colorings and packing, inclu…
Unified bounds for the independence number of graph powers
Aida Abiad, Jiang Zhou
For a graph , its -th power is constructed by placing an edge between two vertices if they are within distance of each other. The -independence number i…
Unified bounds for the independence number of graphs
Jiang Zhou
The Hoffman ratio bound, Lovász theta function and Schrijver theta function are classical upper bounds for the independence number of graphs, which are useful in graph theory, extr…
A combinatorial problem related to the classical probability
Jiang Zhou
In the classical probability model, let be the maximum number of pairwise independent events for the sample space with sample points. The determination of is equi…
Spherical two-distance sets and graph eigenvalues
Jiang Zhou
A set of unit vectors in is a called a spherical two-distance set if the inner products of distinct vectors only take two values. In this paper, we give explicit cor…
