On the unimodality of independence polynomials of some graphs [PDF]
, 2010 In this paper we study unimodality problems for the independence polynomial of a graph, including unimodality, log-concavity and reality of zeros. We establish recurrence relations and give factorizations of independence polynomials for certain classes ...

The log-convexity of the poly-Cauchy numbers
, 2016 In 2013, Komatsu introduced the poly-Cauchy numbers, which generalize Cauchy numbers. Several generalizations of poly-Cauchy numbers have been considered since then. One particular type of generalizations is that of multiparameter-poly-Cauchy numbers. In

Interlacing Log-concavity of the Boros-Moll Polynomials [PDF]
, 2010 We introduce the notion of interlacing log-concavity of a polynomial sequence $\{P_m(x)\}_{m\geq 0}$, where $P_m(x)$ is a polynomial of degree m with positive coefficients $a_{i}(m)$.

The Number of Ternary Words Avoiding Abelian Cubes Grows Exponentially [PDF]
, 2004 We show that the number of ternary words of length n avoiding abelian cubes grows faster than r^n, where r = 2^{1/24}NSERCcs.uwaterloo.ca/journals/JIS/VOL7/Currie/currie18 ...
