Minimal Permutations and 2-Regular Skew Tableaux

William Y. C. Chen, Cindy C. Y. Gu, Kevin J. Ma

Bouvel and Pergola introduced the notion of minimal permutations in the study of the whole genome duplication-random loss model for genome rearrangements. Let $F_{d} (n)$ de…

Higher Order Log-Concavity in Euler's Difference Table

William Y. C. Chen, Cindy C. Y. Gu, Kevin J. Ma +1

Let $e_{n}^{k}$ be the entries in the classical Euler's difference table. We consider the array $d_{n}^{k} = e_{n}^{k} / k!$ for $0 \leq k \leq n$ , where $d_{n}^{k}$ can be interpreted as the num…

The Reverse Ultra Log-Concavity of the Boros-Moll Polynomials

William Y. C. Chen, Cindy C. Y. Gu

We prove the reverse ultra log-concavity of the Boros-Moll polynomials. We further establish an inequality which implies the log-concavity of the sequence ${i! d_{i} (m)}$ for any $m…
