Maximizing the number of maximal independent sets of a fixed size
Chunwei Song, Bowen Yao
For a fixed graph G, a maximal independent set is an independent set that is not a proper subset of any other independent set. P. Erdös, and independently, J. W. Moon and L. Moser,…
On Combinatorial Rectangles with Minimum -Discrepancy
Chunwei Song, Bowen Yao
A combinatorial rectangle may be viewed as a matrix whose entries are all +-1. The discrepancy of an m by n matrix is the maximum among the absolute values of its m row sums and n…
On Explicit Probability Densities Associated with Fuss-Catalan Numbers
Dang-Zheng Liu, Chunwei Song, Zheng-Dong Wang
In this note we give explicitly a family of probability densities, the moments of which are Fuss-Catalan numbers. The densities appear naturally in random matrices, free probabilit…
A comment on Ryser's conjecture for intersecting hypergraphs
Toufik Mansour, Chunwei Song, Raphael Yuster
Let be the cover number and be the matching number of a hypergraph . Ryser conjectured that every -partite hypergraph $\mathcal{H}…
