Some Ratio Monotonic Properties of a New Kind of Numbers introduced by Z.-W. Sun
Brian Y. Sun
Recently, Z. W. Sun introduced a new kind of numbers and also posed a conjecture on ratio monotonicity of combinatorial sequences related to . In this paper, by investig…
On Ratio Monotonicity of a New Kind of Numbers Conjectured by Z.-W. Sun
Brian Y. Sun
Recently, Z. W. Sun put forward a series of conjectures on monotonicity of combinatorial sequences in the form of and $\{\sqrt[n+1]{z_{n+1}}/\sqrt[n]…
Enumeration of Corners in Tree-like Tableaux
Alice L. L. Gao, Emily X. L. Gao, Patxi Laborde-Zubieta +1
In this paper, we confirm conjectures of Laborde-Zubieta on the enumeration of corners in tree-like tableaux and in symmetric tree-like tableaux. In the process, we also enumerate…
Enumeration of Corners in Tree-like Tableaux and a Conjectural (a,b)-analogue
Alice L. L. Gao, Emily X. L. Gao, Patxi Laborde-Zubieta +1
In this paper, we confirm a conjecture of Laborde-Zubieta on the enumeration of corners in tree-like tableaux. Our proof is based on Aval, Boussicault and Nadeau's bijection betwee…
Word-representability of triangulations of grid-covered cylinder graphs
Thomas Z. Q. Chen, Sergey Kitaev, Brian Y. Sun
A graph is word-representable if there exists a word over the alphabet such that letters and , , alternate in if and only if . Hal…
Word-representability of subdivisions of triangular grid graphs
Zongqing Chen, Sergey Kitaev, Brian Y. Sun
A graph is word-representable if there exists a word over the alphabet such that letters and alternate in if and only if . A triangular gr…
