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…

Disposition Polynomials and Plane Trees

William Y. C. Chen, Janet F. F. Peng

We define the disposition polynomial $R_{m} (x_{1}, x_{2}, ..., x_{n})$ as $\prod_{k = 0}^{m - 1} (x_{1} + x_{2} + ... + x_{n} + k)$ . When $m = n - 1$ , this polynomial becomes the generating function of plane t…
