Decomposition of Triply Rooted Trees
William Y. C. Chen, Janet F. F. Peng, Harold R. L. Yang
In this paper, we give a decomposition of triply rooted trees into three doubly rooted trees. This leads to a combinatorial interpretation of an identity conjectured by Lacasse in…

Context-free Grammars and Multivariate Stable Polynomials over Stirling Permutations
William Y. C. Chen, Robert X. J. Hao, Harold R. L. Yang
Recently, Haglund and Visontai established the stability of the multivariate Eulerian polynomials as the generating polynomials of the Stirling permutations, which serves as a unif…
