Bipartite Distance-Regular Graphs of Diameter Four
Huang, Junbo (University of Waterloo, 2014-08-11)Using a method by Godsil and Roy, bipartite distance-regular graphs of diameter four can be used to construct $\{0,\alpha\}$-sets, a generalization of the widely applied equiangular sets and mutually unbiased bases. In ... -
A Characterization of LYM and Rank Logarithmically Concave Partially Ordered Sets and Its Applications
Huang, Junbo (University of Waterloo, 2010-01-21)The LYM property of a finite standard graded poset is one of the central notions in Sperner theory. It is known that the product of two finite standard graded posets satisfying the LYM properties may not have the LYM ...
