New refinements of Narayana polynomials and Motzkin polynomials

Janet J. W. Dong, Lora R. Du, Kathy Q. Ji +1

Chen, Deutsch and Elizalde introduced a refinement of the Narayana polynomials by distinguishing between old (leftmost child) and young leaves of plane trees. They also provided a…

Unimodality of -Regular Partitions into Distinct Parts with Bounded Largest Part

Janet J. W. Dong, Kathy Q. Ji

A -regular partition into distinct parts is a partition into distinct parts with no part divisible by . In this paper, we provide a general method to establish the unimodalit…

Higher Order Turan Inequalities for the Distinct Partition Function

Janet J. W. Dong, Kathy Q. Ji

We prove that the number of partitions into distinct parts is log-concave for and satisfies the higher order Turán inequalities for conjectured by Cr…
